It is meant as a forum-wide database of favorite URLs (like your browser's bookmarks or favorites).
Users with a number of postings can add links and report broken ones, moderators can add new categories and edit bookmarks and categories.
It is like the little brother of
phpLinks which was too complex to integrate cleanly into vBB - so I wrote an own one.
Sorry for not having set up a demo site, but we only own one license of vBB which runs on our intranet.
You have to try it out on your own site, but it's quite easy to set up (cave:
phpMyAdmin seems to have a problem with the SQL script - use
mysql command line program to feed it into your mySQL database).
