Just to let you all know, I started a discussion on prerequisites at http://en.wikipedia.org/wiki/Wikipedia_talk:Ambassadors#Prerequisites.2C_we_need_them Basically, I said that pretty much every non-Freshman course has prerequisites of one sort or another and that by not requiring prerequisites we're sort of throwing them off into the deep end before checking to see whether they can swim. If this is meant for non-Freshmen, then these students should first meet basic prerequisites. If this is meant to be a Freshman-level course, well, they're sort of editing rather esoteric and complex concepts in general for Freshman, aren't they?
