I've added all the Vocabularies to the Recommended Websites taxonomy terms so the category and subcategory show up on the subcategory pages. Sound confusing? I know, I just can't think of a better way to explain it.
I've also added all the tabbed menus to the Subject Guide subcategories. Yay!
Now we just have to finish the data entry. We have 1600+ entries, but I think there are 4500+ total to be entered. Sigh.
