I like putting the editing in the hands of the user. For example, I like the convenience of being able to update the latest version of a song in the original post, saving readers a long slog through the thread. Or fixing a rewritten lyric. Stuff like that. I really don't care if people type one thing then go back and change it. If they ever played games with me, I'd place them on Ignore and move on. But then again, I'm in the minority on that one, so I accept why it is the way it is--I don't carry psychic wounds inflicted by self-editing villains at other bulletin boards.
