I just thought of an idea.
You know how the FiM wiki uses nicknames to identify background ponies? I think we should come up with a few for some of the unnamed background kids in order to identify them better (And also so we don't have to type, "The kid with the [x] t-shirt and [x] hair's shirt turned [x]" and just give them fan names).
I'm not sure if everyone will agree, but it's just a thought. I've already come up with a few on my website.
(And if we do use them, on the character's page, we should put in a trivia part, "This is not the character's official name, but one used by fans to identify him/her")
