I'd like to upgrade to the Developer license to use the User Registration addon but have a question.
I understand there's no built-in approval process and that you recommend having people sign up for one role without content access, then manually upgrade their role when approved.
I'm wondering if the User Registration addon uses WP's core registration process so that I could use a plugin like New User Approve: http://wordpress.org/extend/plugins/new-user-approve/. Or if GF uses some customized registration process so I couldn't do that. Any ideas?
