Approving Members

Greetings,
A simple (I hope) question re: memberships. I have a condo association and I want people to register with their name/email address/condo number. Then, i want to verify they are a resident before letting them into the private area of the site. I suppose the easiest way to pre-populate a member list but I was hoping the moderation of letting people sign up is available. Thanks in advance.

Stay safe!

Rick
