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.

There are a lot of players on this site that used to play there. It is now up and running but not completely. As well as 2 player games, it has quite a few games there that can be tried out against a computer so is a good learning site.
