Add a quick navigate bar to jump across forum sections
Suggest at the top or bottom of each forum page there is a quick jump to alonther forum section slider. So if I want to go from equipment to general astonomy seciton it one click and one page load, not two. Should lighten teh load on your server too!
don't worry, you're not the first to suggest it, so you're not the first that I've had to point out that it's already there
