On most forum softwares, there's are two methods of deleting items - a) not completely remove them from the database, but either move them to a trashcan facility (IPB) or use "soft" delete, which keeps the post in its original position but removes it from view or B) completely remove it from the database. And, of course, every forum has occasions where its necessary to remove posts or even entire threads. Personally I prefer not to completely delete things with no possible way of bringing it back just in case I need to review it again later. What's your preference? Completely remove or just remove a post/thread from view.
