Ok, with all the old threads mysteriously hitting the front page over the last few days or so, perhaps it'd be nice if the "bump" button would sign the person doing it... kind of like the "edi post" screen. Basically allow a person to enter a short "why I bumped this thread" reason and add it to the string of posts. At least perhaps this would discourage people from shamelessly (and anonymously) bumping threads up to the front page that don't really have any reason to be there.
