Hello everyone

I need to re-think the navigation on my site. Currently i am using tabs, and i am very happy with the way that they are making my site more usable, and i have recieved a positive re-action regarding them.

Only problem is, i am about to run out of space for them! What is a type of navigation which i could use which will have the same effect, but be a little more extensible.

I quite like what amazon have done. does anyone have any idea where i might find some code to get me started in moving in that direction? or alternatively have a better idea?

The reason i like tabs is that it is obvious how to get to places, and at the same time it is also obvious where you are.

What sort of navigation do you suggest?
