I think it would be kind of fun, if each team tournament had a discussion board, only readable and writeable by the people in that tournament. It would be a good place to brag, trash talk (LOL) and report wins and stuff.. When the tournament is over, the discussion board would be gone.
I picture the link to the board being on the main tournament page of that particular one. (The page with all the teams listed and the scores) ... Maybe even a link to it in each game?
Obviously it would need a moderator.. Maybe the person who created the tournament? (That might not always be the best idea, though, lol)
I just thought I'd throw the idea out there. I'm sure others have ideas on how it could work..
