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.
jessica: I gave up my membership there because I did not like the limit of 100 games. (yea, it was 200 - but only 100 tournament & 100 regular games - and since I play 99% tournament games, I felt cheated out of 1/2 my games)
... so I only play a few games there now and don't plan on getting a membership again. Dark Crazy Screen Chess is fun when there is enough to start a tournament there.
