Is there a way to collapse the sub cats that I have absolutely no interest in? With as many categories that are here, it becomes a PITA to scroll all the way down to the bottom to Other after I get done in the Dakota sections.

 

Not that i know of, but you can to "My Forums" at the top menu, on the right and then "My Subscription"... and instead of going to the main page to scroll, just scroll through your subscriptions...
