@apollo Sorry about the lack of replies. It's been a tough weekend because it's been a JoCo touring weekend -- @chicazul, for instance, might be interested in the discussion but has been traipsing all over the West Coast with the rest of SuperTrain.
All your suggestions seem reasonable to me! The other question I have is whether we should autoconfirm people at all -- the "spam filter," as it were, on these forums is that applicants have to apply and I (or someone else with mod rights, but usually me) have to log in and click a button to approve them. Should we do the same for the wiki? It'd be annoying, I guess, but there seems like fewer new people who are real people trying to register for the wiki.
