I'd propose two things
1) close threads when we have signed a different player for that position
2) have a thread thats closed for posting, where a dedicated guru links the news of the day. Each post is the rumors for that day, so that same person can edit the post with updates. It would be very handy to see the latest news on players, instead having to wade trough pages of ranting or fapping to find Mark guessing transfers, or Mark quoting GDM/Larizza/those other guys/Curva
