Members Only Content - Admin to approve user - No auto register

[sarnaiz]

I want to be able to let a user register and choose a user name, email and password just like Front-end User Log in, but I do not want the user to have automatic access upon registration. I want the admin of the site to be able to approve and remove users since the site is for a teacher's union, only paid members can have access to the member content.

Looking through the various plugins I'm not seeing this functionality. Is this something that can be added easily? I am not a programmer and would need instructions, or I would need to hire one to make this happen.

Any suggestions are appreciated.

Thank you.
