The languge filter is very messed up. Having certain letters together is not allowed. For example N and G cannot be together. We tried clangroup and it rejected it. Open a game room and type into the chat box the name you want for your clan. If it goes through there ok? Then it should work fine for a clan name. I was unable to have this name "The Old Farts" , but this one was ok "the old farts". Just taking off the caps worked. Why? Who knows.
