I don't think not enough people being admins was ever an actual problem that prevented people from doing useful stuff on LW wiki.

To keep things clear, I (as opposed to David_Gerard perhaps) never meant to suggest that adding some admins & vandalfighting capability would make the wiki take off. (I'm not too clear on what the wiki's function is, in general.)

I just wanted the admin bit so I could deal with the vandalism that routinely passed through my RSS feed - I'm willing to contribute to that extent but not much more.
