I like it. Though I've only been a free member for about 8 months or so.
A couple times I just about joined as a paying member but then they would
have a server outage that would last a few days or even a week or more.
So
for now, I'm staying only as a free member.

The only major outage was caused when the webmaster had to change hosting
service when the previous host wanted to charge an exorbitant new rate.
Chessworld.net has one of the cheapest subscription rates around and the
webmaster wanted to keep it that way. I've tried out most of the turn-based
servers, but ChessWorld is the only one I subscribe to.
