Membership moderation in buddypress

I've been reading around tons, and tons of forums and trying dozens of different plugins - I'm desperately trying to find a plugin which provides membership moderation in buddypress...

That is, you can sign up - but you don't get access to the site without approval from an admin.

I thought I had hit gold with this plugin - as it should do exactly what I want it too..

http://wordpress.org/extend/plugins/bp-registration-options/

But it doesn't work in the current buddypress....

I've read these forums for an answer - and further a-field... but cant find one. Does anyone have an idea?

I've got to launch the site tomorrow... so I'm kinda stressing...

Cheers,
Rob
