Just to simplify a little, you can take out the _ in the category name on the Space page. It should work if you just have spaces in place of them, and that will make it a little easier for people to type/remember. Also to note: case counts, so make sure all future references to your category have the first letter of each word capitalized.
I'm really glad you set this up! There are many Stanberrys / Stanboroughs / etc that need to be sorted out!!
p.s. I just added the Stanberrys, et al from my watchlist.
