BuddyPress.org

(I’m going to try to be helpful rather than just telling you to go elsewhere. I want Buddypress to grow, and users helping users ought be part of that. I’d also like the forum here to be a useful resource. So many threads at mu.wordpress.org are just cries for help with zero replies. That sucks.)

wordpressfan, I’d probably approach this using Roles. I’ve never done it, but you could set the Dashboard user default role in Site Options to ‘Inactive’. That would allow you to monitor signups, and approve as necessary, I’d imagine. As long as users know that there is a process in place where they have to wait for approval. There are plugins out there that allow you to create custom roles, too, but I’ve never used them.

In terms of the registration emails sent to you as admin, this is also a WMPU thing, not on the Buddypress end. I’m sure I’ve seen plugins that allow you to edit these, but I can’t find them for the life of me. If you’re comfortable with hacking the WPMU core (and rehacking after updates), you can find the place these emails are generated in

function newblog_notify_siteadmin

in wmpu-functions.php in /wpmu-includes

off the root of your WMPU install.
