BuddyPress.org

I don’t really understand the whole plug-in thing. I tried to install a plugin for registration, but then I couldn’t figure out how to get it to display a form in the page named “Register” in my Pages tab. I have the basic pages set up, but here is what I’d like to do…

Membership – I want to be able to send potential members invites. They can also register themselves, but I want to grant approval. There will be 3 registration levels.
I want registration pages requesting Name, City, State, and email address. I would like for the City and State to be in drop downs. During registration, I would like for the member to agree to disclaimers and legal agreements. Member profiles are free, however members will have to pay a subscription in order to communicate with other members in their respective level.

Profiles – Member profiles will only show the member’s name, city and state, “About Me”, and a photo album. The only field the member can edit is city/state and About Me. Only an Admin can edit the member’s name and photo album.

Search Function – Anyone (unregistered visitors) can search for members on the site using the member’s name and location. I want a drop down menu for the city and state.

I would like an area where any member can post a picture of themselves. They are allowed to post two pictures per day.

Am I able to do all of this using Buddypress plugins?
