CUNY Academic Commons

User registration spam is prevalent in BuddyPress.
One way to dramatically decrease signup spam is to restrict the email address domains that users can sign up with.
WordPress multisite has a native option called “Limited Email Registrations”. But this option requires you to enter the full email domain. For example, if you only wanted to allow .edu email addresses to register, this is not possible.
This plugin restricts registrations to the email domains that you specify and works in WordPress single-site and multi-site.
Plugin was developed for the <a href="http://commons.gc.cuny.edu" rel="nofollow ugc">CUNY Academic Commons</a>. Licensed under the GPLv2 or later.

Tested on BuddyPress 2.5, but should work all the way down to BuddyPress 1.6.

This plugin allows you to turn of or shutdown registration via Buddypress, without effecting other functionality.
I built this as I don’t like the way Buddypress does registrations but liked most of the rest, but you could use it if your site was full or invitation only for instance.

LH Disable BP Registration

Shuts down registration via the usual Buddypress method, all other functionality is not effected.
