I'd like to allow users to specify one (or possibly more) RSS feeds in their profile, and have them submitted to the site's RSS aggregator. This would allow the users to post their own blogs, and have them aggregated & available to everyone. By "user profile", this could be either using core profiles, or Node Profile (profiles as nodes).

I see one module that provides this, but only for 6.x: http://drupal.org/project/profile_blog_info

Is there anything out there already for 5.x that provides this functionality, or something similar?

Thanks for your time.
