Organise the threads into subject areas, e.g. prospective students for maths and english extensions 2, language, history and music extensions; and post up an FAQ for each Year 12 extension so that the place isn't clogged up with threads of 'what's it like?'. So that if let's say someone's worried about gaining entry to 4u maths (which I've seen this year--2004), they post their thing in the 4U maths subject area. Also a list of prospective Year 12 topics would be good per subject so we don't go tunnelling through all the forums for each subject we do.
Or maybe we can put them into broad course areas and extension feeding off will be put in a sub-area underneath, e.g. have a 3U maths area, and a small sub-area for those considering 4U in Year 12 under that 3U section. Same would go for english, languages, history and music extensions.
For general stress relief, e.g. the whole omg it's year 12 after sept hols thing and half-yearlies and yearlies, etc put that in a 'help' area or something similar of the sort.
Hope that was constructive, well, not too critical I mean...
