Re: buddypress-mu possible yet?
Check out “/wp-admin/users.php” and snag the code from there. It should give you more than enough examples on ways to filter the users on that specific site. I think it should include pagination, user type, etc…
The key for you will be making sure that the right members are subscribers of the correct site. If you have multiple domains or multiple registration pages (for each site) that should be pretty straight forward.
