Just a quick note that you may want to make sure you are using the categories consistently. Wiki categories are both case and space sensitive.
For example, Primary Sources =! PrimarySources, and, Hss =! HSS
I have already changed any pages with PrimarySources to Primary Sources. However, some pages are still tagged with Hss when it should be HSS.
Please feel to revert the changes if you had intended it to be two separate categories, but I thought in this case, it was safe enough to assume it was meant to be the same.
