Collapsing USA and United States categories
I see you haven't been active on WikiEducator of late, but wanted to let you know of a change that I'm making. There are currently two categories for the US: Category:USA and the one you created Category:United States. The USA category includes many more pages, and we don't need two categories, so I'm going to discontinue the United States version. Hope that's not a problem. I will recategorize your user page under Category:USA.
If you restart your work on WikiEducator, do pop by and leave me a note!
