Yeah, the promos came out first, but the proper single release was in that order, so that's how it should go, IMO.
As for Kittens, there are certain guidelines for articles on Wikipedia. One of those is notability:
http://en.wikipedia.org/wiki/WP:Notability
It will not pass that criteria. That's the same reason the Confusion article was deleted.
I've become increasingly frustrated over the last year by the constraints of Wikipedia. It is simply not an appropriate venue for all the Underworld trivia that we want to put down.
