works like a charm. I am using ExUserFolder and it's membership function to implement member-wikis in place of an old PTK mishmash.

I've set up an XUF here on just for test purposes. Here's an easier (non-ZMI) XUF admin interface I'm working on. To install: copy this (structuredtextdtml) page to a folder at or below your acl_users, make sure you have Manage Users permission, and manage away.
