While I know you have one, and have used it on occasion ... I always forget that the links are under Directory and Resources is just your button ads and it takes me a bit to remember how to go find the actual links cause I inevitably hit the Resources link looking for sources. Maybe combining those 2 categories would make it easier ... or show the link categories on the left at the bottom instead of the thread links?

Putting up a resource directory within the Forum is also an idea if you mean to keep them locked and you oversee any additions to each section?
