(1) Can I add as many questions to the user's profiles as I want?
(2) Can I change those questions, add more, delete some, etc. any time? If so, what happens to the old answers? Are users automatically asked to go back and update their profile questions?
(3) How can I allow users to search for other members by Zip code, and show the members' location on a map within each profile?
(4) Can I set up Dolphin so that EVERY profile is readble by ANYONE (the entire public), but new members must be approved by me?
(5) Can I set up two different types of profiles --- sort of like "buyers" and "sellers" --- which could search for each other... by location... (zip code)....?
