Buddypress Membership registration

Hi

Currently when a user registers on my site to become a member they receive an email to confirm registration and they are then automatic members.

Is there any way to make them "Apply for Membership", receiving email stating we are reviewing their application and will let them know if they are successful.

I have tried BP-Registration-Options but this is outdated and conflicts with my current install of Buddypress 1.6.5.

I have gone through wpmu community and anything related appears out of date.

Any thoughts?

thanks

Michael
