Pitch, if you have finished all your games in that tournament and will not go any further you can message Fencer and he will remove you from that tournament which will free you to join another.
Pawns cannot have unlimited tournaments, there has to be some restrictions or what would be the point of paying for membership? As a rook you would be allowed to enter unlimited tournaments, as well as many other benefits. It is definitely worth the cost.
As for the service, you really can't get better. Fencer is on hand pretty much every day to resolve any problems, which are done immediately. He listens to everyones suggestions and ideas, and acts on them.
As a pawn you have many benefits here you do not get at other sites. You can play all the games, and variants. You can have unlimited moves per day, and join a tournament. You also have the benefit of some of the friendliest players on the net! lol! If you are not happy with your restrictions you really should consider membership, as a rook it is unlimited everything! I have never looked back since buying mine, I'm very happy with my membership benefits and highly recommend it to everyone.
