Each skin has the ForumJump feature, so you can jump from one forum to the other (I may look for a way to add this to every page).

You may try the LiteSkin, this one disables a few images and also has the SubForum dropdown installed. To speed things up even more, you could toggle display other users Avatar/sig pic off in Your Control Panel/Account Options. The subforum dropdown may be something to add to all skins, could all users give this a look please (currently only used in LiteSkin) and voice whether it would be a good thing to add?

We'll give the Category name another look.
