I think there should be a link in your account settings if you have over 5 posts to create a wiki account instantly. That should prevent spam, avoid over 9000 unused accounts and still be an easy way. Of course one could still mail the wiki admins to get an account created.
Also according to your criteria I qualify as a wiki admin/staff.

SPASM can do that too but it's really bitchy when it comes to file format.

If the test itself fails and it doesn't work after that then your touchpad is most likely dead.

If mediawiki then it should be like on WikiTI where you have to privately ask for an account to prevent spam bots from even reaching the site.

Yeah that works.

Omgwtf that is awesome.

Well, what they said. It does look awesome. Keep it up !
