A mod witch will add a new links page to your froum. fully ACP insterface, from where you may add/delete and update link categorys/sub categorys and links.
First create a category. Second create a sub cat. The enter a link name. When done, go to that link name and click edit. Now activate the link and add the url.
Thats it, works for me.
I'm playing with the tables right now, but here is my links page.
