Lynne, this is brilliant! I upgraded my forums (drzforums.com) last night, and ran into a few pain-points. Using your instructions, I created the navigation tabs that I would like, reusing all of the sub-menu links from the "Forum" tab. Now, I'm left with one more question, which I am having difficulty finding through search.
There is one "Quick Link" that refers to a javascript code bite. How do I program "Open Contacts Popup?" Can you point me in the right direction?
Thank you for the trouble you went through to document the tab creation process!
Heh... I guess I'm going to have to setup some conditionals for several of the sub-menu items.
