BuddyPress.org

I want to manually approve user registrations in our backend rather than letting them click a link to activate their account. I was able to remove the activate link on their end in the email they receive, but am wondering how the user can get an email notification once I’ve either activated or deleted the account request from the backend? As of now it does nothing when I activate it. I also want to change the verbiage that appears on the page after they submit their user registration information and cannot find out how.
