I'm looking to create a site that requires people to log in, in order to submit a post which I can then accept it or not to go on main site. Also if they would like to comment on other posts they must be signed in. Also would like on registration to ask for zip code so can build up a user base then at some point would like people to be able to search by zip code to find others. Overall would like them to log into the site and not into some WordPress sign up. Hopefully this made sense if you could direct me toward the answer or advice much appreciated thank you.
