how can visitors build there own page?

Does anybody know of a program or software, that I can get that would let visitors to my site build there own page. Like a profile page where they can add there own pictures, have a friend list, mail and a bulletin board. Thanks

 

There are some community building scripts on http://cgi.resourceindex.com/ that look good. They offer many of those options.

 

Thank you again. I noticed you on another post I had.
