Or how about an intermediate screen that pops up the first five or so times a user posts that says ``Are you sure this isn't in the FAQ?''

Back when I was in college, the Usenet software we were provided was hacked to say, when you tried to post, something along the lines of ``The post you're about to make will be sent about the world, potentially using hundreds of dollars to propagate. Are you sure you want to post it?'' Really annoying, but it scared the bejeezus out of me the first time I saw it.
