how is it possible to shutdown all nodes for maintainance ? Are all nodes run by the devs ? Can ordinary people run nodes ?

What you call effectively a few months was about half a year. With multiple extensions.
Poor communication is also complete and utter crap. We posted on all forums, and linked to those postes on all channels, PMed everyone on btt twice and even sent messages through NXT to the accounts we knew hadn't registered yet. We didn't have e-mail addresses. That's not mentioning the 100s of pms I answered to people that actually spent 1 minute to just ask if something was unlcear. So what beyond that would you have expected ?

Redepmtion didn't go perfectly but you are making it sound way worse than it actually was. You say there are at least 30 people with your problem. Well there are over 1000 that redeemed without any problems.

You got banned from the forum probably - and this is really just a guess - because you opened multiple threads like this and posted about this topic in every active thread you could find even if the thread wasn't even remotely related to redemption. At some point cleanign up after you in the forum is going to be too much of a hassle. I'm making this guess because i thought about banning you twice but then didn't do it. I guess someone else just finally had enough.

How can you have a hard time removing the light wallet from your system? It's just deleting a few files since there is nothing being installed.
Are you walking about the installer ?

A QT wallet for NEM is never going to happen unless someone from the community builds one.
What's being worked on are thin-clients that basically only use web technologies like html and js.
So the plan afaik is to turn the lightwallet into a fullfledged, feature complete client and discontinue NCC down the line.
At that point you have 2 scenarios:

1) People that aren't very technical can just download the lightwallet fire it up (and it'll work without anything because you literally only need a browser) and connect to a server that's already running somewhere on the planet (hence the supernode program).

2) People that are more tech savvy will run their own Servers to both support the network and be even more secure. In day to day life though when they're only making tx they'll also only be using the lightwallet.

This will kick the usability up a considerable step.
 
It should have been done a long time ago but manpower is limited.

Obviously you need to trust the server you're connecting to since it's watching the chain for you and could theretically lie to you about it's contents. So while it could not steal any of your funds it would theretically be able to trick you into think e.g. a tx is there when it really isn't.

To be clear: This is not a specific problem with NEM. In any blockchain if you're not keeping track of it yourself you have to trust the party that does this for you.

thankfully the limit for supernodes can be controlled without doing anything to the chain so it should be possible to adjust for such rallies (and then possible drops) relatively quickly.

I don't think it needs to be the main focus but a better client is definitely direly needed. Afaik it's being actively worked on though.

Yeah, everyone finds that process way to cumbersome. It's a gernal problem in crypto land. I'm hoping Apex will help us out.

Personally I'd wait until NEM has an AE so those silver coins can be issued as mosaics and redeemed or sold. This would of course mean that it wouldn't happen for another while but it seems like the most logical way to do it at least to me.
Technically they could be issued right now since mosaics are already in place but without an AE it seems rather point less. Of course it would be totally fine for people that want to redeem i.e. get that physical silver coin.

I realize that this does not solve the governance issue.

Another thing to consider is that there is probably a good chunk of original stake holders that no longer have access to their original account. I wonder if it's even worth to issue mosaics to those accounts. I guess it wouldn't really matter but I still somehow feel like that would be a shame. No biggie - just something to consider imho.

Right now I don't know of any way to get from XEM to FIAT.
Looking for a private buyer may not be the worst idea. Of course you need to find someone trustworthy.

Are you sure that particular project uses the public chain ? Just from the sound of it I would have guessed it to be using mijin.

Maybe you should tell them that

I'm neither a moron (i guess that's up for debate) nor a daytrader and I don't "get it" either.i can give you sound reasons for why I didn't invest in Lisk. So hold your horses there because I think there are plenty of lurkers in this thread who are on the edge about the project or just wanna see where it goes without investing. Your attitude however is nothing but damaging. Just sayin...

Come to think of it. Soon NEM will be coded from scratch. twice!

your two don't prevent anyone rom running their supernodes.However 2 supernodes under the same ip / same home uplink are not as valuable to the network as 2 supernodes in 2 different locations which is why only one should be subsidized by the rewards.
Yes that would be okay. 2 boxes, 2 uplinks, 2 ips, all good. (and frankly noone would do the investigating to ever find out about that)

He asked what features is actually had not what was promised.
I don't mean to hate but 80% of that stuff never actually happend and the rest is questionable because there never was a proper technical explanation.

Where are you watching it ?
It seems there is something wrong on CMC. At least it look weird and I wouldn't have expected Lisk that for down.

That's not really what's the big deal but to answer your question - if done right the performance and efficiency advantages can be pretty massive.

and I guess what the rest of us can expect from those investors are useless threads like this ?

Nope, I don't think so.
