Please keep things positive. Best advise I believe is to try out different sites. Find what works well for you. If you don't like it, don't go back and try another site. Nothing says you only have to play on 1 site. At one time, I played on about 6 different turn-based game sites.
coan.net: I believe they said on the English site they would add more games once they had 100 paying members? Seems like if they added more games they would get more of the guest already there to join as paying members! Looks like 73 now so have a long wait
