I mined for a few hours and it worked pretty great. The payments arrived hours later but I guess it's pretty normal.
After a few hours either my connection or the pool started being sluggish so I had to stop. But it was probabilly because I had 4 cryptocurrencies syncing at the same time.

Great pool though, functional and simple to use!

Also, after mining in the pool for a bit I solo mined for fun at 200 KH/s for 2 hours and found a block! I have like 18k IFC now

I had the same problem on my mobility radeon hd 5470 and I solved it by lowering my working set to 128 which then gave me a different error which i solved by removing thread-concurrency from the bat and letting cgminer set it. Resulting settings:

I personally don't like to rely on third party services for a currency that is supposed to be completely decentralized and independant, the safest way is to send everything to paper offline wallets.
