It could appear based on a user setting that could be turned off once someone knew there way around (and was past the point of not knowing about posting conventions).

Better yet, it could be turned off automatically. After a user posts <x> nodes, it can be safely assumed the user knows what he's doing. The only 'problem' is determining that x. Is it 1, 5 or 10?
