I haven't done much outside of the basic drupal stuff. In previous versions I've used menalto gallery plugins and maybe a music player; but since I reinstalled with drupal 6 I've been pretty basic. I use it more of a framework for some custom php database queries (which I assume you know you can enable php as a valid type to include along with filtered and full html).

I did a couple of searches at the drupal site for weblinks and one post mentioned it perhaps having to do with adding a vocabulary for them in taxonomy - but a url part he had seemed to hang up my browser when I tried it on your site so I won't type it here. Speaking of the taxonomy stuff - this is all new to me but I was working with it today trying to create a protected forum for only certain members (a work site - nothing exciting) and that alone is difficult to figure out.

If you are on drupal 6 or 5 I guess I would just recommend that you check the admin blocks and menus sections to see if maybe you have some useful items disabled and maybe something will work for the new video browse.
