I dont like the idea of multiple skins for one reason: people who do the blending thing with their banners to blend with the color of the skin....it'll be useless because it wont look right to someone who is using a different skin. You'll have to use gifs for that..and its harder.
I get it. Look at my sig and avatar. I changed it from the old vB2 colours to match the new default skin and will now have to do it again to match this one. The problem being that if it matches this one for me, it'll look stupid if someone else has a different skin. I'll leave it as it is for now as an example, for those who don't get it
