Have you set up My Flyertalk with your preferred forums stored on it? You'll have a menu there of only the forums you want, and you won't need to jump all over as they'll be in one place, easily accessible by clicking on My FlyerTalk.

When you enter a new forum, click on 'forum tools" and you can subscribe from there. After that point, you just need to click on My Flyertalk and all your forums will be right there.
