Module / Hack to autolink and sort by user...

Hello,

Started using Drupal to re-develop my site about two weeks ago, and I feel as if I'm starting to get a decent grasp on it (seems much more flexible that *nuke, mambo, etc).

Here's what I'm trying to do. In my user profiles, the user will list in a textbox their favorite musicians.

I want the output (on the user's profile page) to make each band listed a clickable link. When clicked, it would take the user to a page that lists other users who also listed that band.

I'm sure it can't be TOO hard.
