I'm running a radio stations site using postnuke (www.subcity.org)

We badly need a module would allow djs to publish and edit their own profile pages but not be able to damage the profiles of others.

Ultimately, we would like to link this into our schedule page by show name (autolinking)

I would be really grateful for any suggestions?
