page jump?

Well what I am looking for it...well let me say why first.

I have a look list of categories and don't want to make categories to go to other categories.

So what I would like to have is say a listing of the different categories at the top and when someone clicks on one it jumps down the page to right category.

then have a return to top by that category.

EXAMPLE
all these are links at top
Forum categories listing
general a
games
web design
food
life
etc..
etc..

All these are forums down below
--------------------------------------
general a
_______________________
Games
web deisgn
food
life
etc..
etc..

If I click on something under forum listing it would take me to the the forum below

Any ideas ?
