Help with Nav bar hack

[DDad]

we have 26 forums with 350 subforums(forumdisplay or categories)
When someone registers they register with a subforum or categories in mind.

How can I add the forum or category they choose when the registered to the nav bar when they log in? (For easier navigation)

I think this is similar to a weather hack with a zip code in a field?

How are they selecting the forum they are signing up for...

Just like the weather hack they would enter a zip code and their weather shows up.
In this case they would pick from a drop down of forums, soccer,football,baseball,ext. So when they sign in it would have that forum on the nav bar so they don't need to search for it.
Thanks for the thread,I may use this along with what I'm looking for.
