If you've done extensive work playing with MediaWiki's permissions for user groups, could you please contact me? Or if you know of an easy way to let non-techies manage user groups and rights in MW, I'd love to hear from you. We need some advice at work for implementing varying levels of permissions for posting (and no, this doesn't mean ALA is locking down all of its wikis).

Catch me at jlevine@ala.org or on AIM at cybrarygal.

Thanks!
