Requested it before as have probably others. It would be helpful to pin rules of certain giveaways or threads (enforcing local rules and so on) to avoid unnecessary spam. For instance, I have a thread for the Bitcointalk Premier League pool with the local rule that only people who paid to play in it can use that thread as it's for discussion of the pool and results, but you obviously get people posting in there that didn't read the op. It would be helpful if that info could be pinned to the top of every page.
