Its a team or 13 players or more but the team play other clans and the captain will pick who is playing and who is not playing but if you are playing it mean when you see person you are playing online you play them and post the score on forum and on clan chat.But every player has to be active if not captain can take you out of clan.If you want to join a clan plz post on one of the clans thread and captain should get back too youor you can post on http://www.funkysnooker.com/viewTopic.do?topicid=4777 and captain will ask you to join they or you can privte message a captain and ask them.
Can a Moderator to cap this and make it Sticky plz.

And there are some clan captains who pick players for their clan matches even though they know they are unreliable. Then the opposition ask for a replacement and the clan captain does nothing about it.

You should watch out for those type of clans because they're the ones that waste everyone else's time.
