I may be missing something obvious, but
I put ~400 shares into the last btcworld.de block and I was credited for 0.
Just a heads up.
Edit: Worker shows up as active, i'm attributed with shares *during* the round, just afterwards it says 0.
The same thing happened to me. I mined over 10,000 shares over the last two completed blocks there and received nothing.
My balance still says zero. Their stats are messed up too. Every language gives a different total share number.
Probably best to stay away from this pool.
