Hmm!
Instead of having to delete all of the old things (some people actually DO like to read though them old posts, such as me), i think it would be better if the leader / admins could designate specific posts as 'usefull'. They could then go back in the old archives and sort the usefullness out. all of these 'usefull' posts would then appear chronologically in a tab much like the current Hints button. No need to delete to sort! Instantly mark the goodie post instead!!
