Maybe it's old news but I'd still like to point out:

For those that don't know, do not use
http://nlg.pool.mn/. Untill all coins are paid (and maybe after even don't) do not mine over there. After issues 'in the back-end' nobody seems to be getting their coins even though the issues seem to be over. I still have a 12,5k of Guldencoin over there but they're not paying out, they're not responding to mail and your manual payout get's stuck, ergo, nothing.

Honestly, I would never trust a pool which advertises to use a fee of 0% ALWAYS. I'm running a decent pool myself, dedicated hosting, which costs me quite a few euro's every month. The fee is what is helping me in getting the hosting paid every month... and to be honest, I nearly break even some months, which makes this more like a hobby project I spent my own hard earned cash on.
So please feel free to join a stable pool which is actually paying out every few minuted (fully automated).
Running on a super charged
dutch server (dual SSD disks and 32GB RAM) to ensure smooth mining and a very stable experience!!!
