I was recently advised by a friendly moderator that when I want to create a tag, I should not just go ahead and create it. Rather, I should bring it up at Meta.
However, there was a question about a "diversity" tag already, and there someone said, Just create it on the fly when the need arises. Which is what I did, since I think this one is a slam dunk. More and more universities are working hard to recruit if not diverse faculty members, at least culturally competent candidates.
