40376 php Gift Registry Edit

I need to edit the php gift registry script, [login to view URL] I have already made some necessary edits to it but I don't have time to figure out how to do the rest as I am not that well versed in php/mySQL. I need the following edits: Create 2 categories of users (one category for people who need things, and another for those willing to buy gift for others) Fix the messages/e-mail section so sent/received messages appear when user logs in. Add users address to the shopping list. Create admin view of all items requested and thier status. Add announcement section where admins can create announcements that show up on the user's screen.
