With base difficulty at this low at 0.00031592 , I would recommend all CPU miners directly mine from wallet without Cheetah software.  Just use GUI wallet, -> Click "Help" in menu,
click "Debug window",  click "Console",  type in below command:
setgenerate true


To stop mining, type in below:
setgenerate false

Yes.

Advertising, or more proper word, marketing.  Yes, you raised very good point on lack of attention on NENG.

At initial dev stage, we have been focusing mainly on "tech" side, or specifically "security", or "decentralization" side of this coin. To make NENG a solid footing.
In my opinion, an altcoin has no future if the 51% attack risk or security of a coin issue is not addressed.  Bitcoin, or even Litecoin/Dogecoin are so much better,  much more secure than most other small altcoins due to their huge energy cost mining barrier. That is why my focus has been on that up to date.

I think after v1.2.0 upgrade,  burden on pure "tech" side is lessened.  The focus would be shifted toward more toward marketing of this coin.  I would hope community members or investors can pick up more actual marketing with word of mouth tasks.  For dev point of view, I am starting to think of marketing related dev on NENG, for example, a reward system on NENG because people love reward.  Masternode coins is kind of reward, Electroneum cell phone mining is essentially a reward.  Coinbase paid $100 million for earn.com, essentially earn.com is watching some videos and get some crypto reward.

We will develop a kind of reward system around NENG on dev work.  It is too early and I am still researching and exploring this field.  I can not say too much on that. But after 2019 Q2,  dev work will most likely shift toward "marketing" heavy work such as reward based work to attract more users and get bigger attentions.  Just pay attention to this bitcointalk ann and discord for our future announcement on NENG new directions.

New Coin Name: no.  This project is for New England Coin. I do not see any better name for this project. 
New Design:  Yes.  I am not good designer.  I expect NENG community to grow  larger to take over the decision making on this kind of thing. As dev, I have to start to use
some graphic. This is decentralized coin and project, I fully foresee graphic design is most likely to be outside DEV team's domain  and to have major change in the future.

We are now 2691 blocks past the forked point.  The longer the block length over the forked position, then the more solid confirmation of the new dynamic anti-instant mining algo.

NENG blockchain is under attack from miner with IP from EU or UK.  Someone with old wallet version probably applied huge instant mining over last night, probably in private chain, then put the chain in public now.  Here is my wallet peerinfo:

{
"addr" : "206.189.113.92:6377",
"services" : "00000003",
"lastsend" : 1550544393,
"lastrecv" : 1550544393,
"bytessent" : 1920,
"bytesrecv" : 6156,
"blocksrequested" : 2,
"conntime" : 1550544357,
"version" : 70002,
"subver" : "/Satoshi:0.8.7.5/",
"inbound" : false,

"syncnode" : true
},
{
"addr" : "51.77.116.183:6377",
"services" : "00000003",
"lastsend" : 1550544359,
"lastrecv" : 1550544359,
"bytessent" : 229,
"bytesrecv" : 4465,
"blocksrequested" : 0,

"subver" : "/Satoshi:0.8.7.5/",
"inbound" : false,
"startingheight" : 280817,
"banscore" : 0
}


Note the total block length is only 276181,  the lower IP has 280817, so much longer block length.  This attack is not going to work because those extra blocks probably have many block times
within Spike difficulty (3 seconds) range and they are mostly likely obtained from per-forked old algo. Those extra  4,636 blocks,  or extra 92 million NENG will be deemed invalid in new v1.2.0 core wallet full node.  

Just a warning for big ASIC miners:   do not throw in big hash rate thinking that you are going to make killing on rewards because base difficulty is low.

current is boom time for small ASIC/GPU solo miners and CPU miners.   Because the base difficulty is very low,  big ASIC miners are not doing well, only getting some rewards.   In fact, I would say small ASIC miners and GPU miners obtain more rewards than big ASIC miners now.
This  is because of reset last night, the base diff is slowingly going up, but not very fast.  

When the base diff goes up in the future above 1, big  ASIC miners will do well then. Not for now.

CPU mining is normal with Cheetah_Cpuminer software.  My 2-core linux PC mined many blocks with CPUs since last night

Looks normal so far.  Try to search one block hash against the  explorer, make sure the block is there:
http://nengexplorer.mooo.com:3001/

The block diff has multiple levels.  One is base level,  currently at    0.000772.  Another is CPU mining level, which is 0.00024414.   Last night for a while the base level was same as
CPU diff level.  There is Spike level 244,000 difficulty, which is rare.  So far no block was mined on spike diff level yet, in theory it could, but not expected to happen.

The version is still "version" : 80705.  For two reasons we did not change this. One is that this is fork off version from Litecoin (or same from bitcoin) that our dynamic diff algo is based on.
The second is that we do not want wallet version to be disclosed to hackers in traffic.  Our network is safer if  potential attackers do not know peers software versions. We also expected to update our wallet versions frequently in 2019 and beyond.  Each wallet update transition period has potential to be attacked by 51% attackers.

Make sure that you use the v1.2.0 wallet.  Then you can addnode using the IPs here:

CPU mining were back just minutes ago.  This was likely to be difficulty reset period.  It used to be super fast movement, 1 second per block for ASIC miners for 1440 blocks.
Because v1.2.0 upgrade removed instant mining, the reset took much longer to the point of slow movement on very low diff.  

But now the base diff is up so that CPU mining is back into play.

One Major Issue found on v1.2.0 ,  for unknown reason,  as soon as ASIC miners stumbled into 244k difficulty zone,  NENG is no longer CPU minable.  virtually 100% of mining rewards go to ASIC or GPU miners,  pool or solo miners.

Because CPU mining feature of NENG is important coin feature. This is major issue.  We will give a day tomorrow to observe NENG blockchain movement and work on the solution.
Until further notice from here, it is not worth trying Cheetah CPU mining for now because pretty much 100% of rewards goes to ASIC or GPU miners.

Update on solo-mining small ASIC rigs:  gave up on solo-mining setup messing.   Only good for couple of hours and then were hit with "all pools are dead" error.  
Not worth the effort.     

Re-join the two pools here at NENG.

It appears that now it is exclusive mining period for ASIC/GPU miners.  There are probably no rewards for CPU miners for now. Not sure why.  Still learning and studying the NENG blockchain.

The ASIC miners got stumbled into 244K zone, thinking the difficulty base level is 244,000.  Actually big pool ASIC miners are not doing so well, Blocks are mined by big ASIC for sure, but not that much rewards.

The big winner now is small solo ASIC/GPU miners.  I actually now am running a small ASIC USB stick at 3 Mh/s hash rate, getting blocks virtually very two minutes. Probably true if someone runs a GPU solo miners for similar results with big rewards.  For this period,  the v1.2.0 is encouraging small ASIC/GPU to go alone with solo mining setup.  

Found one issue after the hard fork,  the original plan was to raise the spike difficulty level within 3 seconds to the level of dogecoin.   The current dogecoin difficulty is about 2 million,
litecoin difficulty is about 7 million.

However,  the v1.2.0 math is off by 10x.  My mistake. The spike difficulty is only 1/10 of dogecoin level. Here is screenshot I obtained on the small ASIC rig that we ran.  Below screenshot is from  either Findblocks or Miners.rocks pool. We actually tested on both pools and got similar screenshot like below:

https://ibb.co/k0xYgGT


Note in the screenshot, the mining pool said "Network difficulty changed to 244k".    The desired result is 2440k.  
ASIC mining pool should set difficulty to the base level, which is 16 or 25 whatever, probably several orphaned blocks got ASIC pool confused and used the 3 seconds spike difficulty instead.
Whatever, this tells us that the spike difficulty is only at 0.2 million level,  one tenth of dogecoin, or 3% of litecoin difficulty level.

On the otherhand, NewYorkcoin  current mining difficulty is  928.  The NENG spike difficulty is 263x larger than that of NYC.  This issue is not so urgent to fix.  We will table it for now
and do a bundled security upgrade in 2019 Q2 together with other issues TBD.  

Please check out the whitepaper v1.0.  Our recent research on 50 blocks after fork confirmed that CPU miners (window, linux or mac desktop/laptop miners) obtained 36% of block rewards, ASIC only mined 66% of block rewards.  CPU mining rewards are significant.

NewEnglandcoin (NENG) has hard fork today on new core algorithm v1.2.0,

Research on first forked 50 blocks confirmed that of the first forked 50 blocks, 17 blocks were mined by CPU miners,  33 blocks were mined by ASIC or GPU miners.  In other word, the first 50 blocks under new algorithm, ASIC/GPU miners got 66% of total rewards, CPU miners obtained 34% of total rewards.  Ratio split on ASIC/GPU/CPU miners are not constant, could be subject to changes depending the difficulty and mining rigs distribution.  However, this 66/34 split of rewards is within expectation of our original plan for the v1.2.0.

NewEnglandcoin v1.2.0 was released to have hard fork to enable anti-instant mining and anti-51% features.

NENG v1.2.0 Hard Fork has been major success!

Research on first forked 50 blocks confirmed that shortest block time was 4 seconds.  Essentially fast block time or instant mining has been stopped.  Historically, fast blocks would
be 1 in 20 blocks , some times 1 or 2 blocks within 10 block stretch.  The dynamic diff algorithm implemented in v1.2.0 is working.
