I don't see a Tag that says OTHERS to put our stories in. I have a lot of background ponies and yet none of them are the tagged ones.

Simply adding an actual OTHER Tag would help or maybe a Tag that says Citizens of Ponyville would do the trick. On that, I believe many would agree.

I'm not entirely sold on that. There are already tags that cover multiple characters (such as Diamond Dogs and Dragons), so who's to say the Other tag doesn't do that as well?
