In the beginning............(sounds biblical, lol), we were able to edit our posts and even delete any post or thread that we started, and there was a particular forumite who was banned and re-emerged under two different names, I believe. His final name was Mitch and he made it a practice to begin threads, that drew lot's of thoughtful, often well crafted posts on them by fellow members, and then sometimes days or weeks later, he would decide to delete the thread and everyone else's posts disappeared with it. If my memory serves me correctly, I believe it was then that the system of giving us fifteen minutes to edit or delete a post or a thread was initiated . I do feel like a forum historian, here sometimes. lol
