Oh, indeed. Never seen them, but I think I never paid attention to any footer so far, so maybe they could be more highlighted.
On the other hand, like usual, the people who should read them the most, are probably the least likely to do so. Also the forum is somewhat self-regulating now?
I read quite often, when someone misbehaves, others chime in and ask them nicely to not do that here.
(They're also not in the footer of the comment page and a link in the otherwise empty header could be useful for new users.)
