So here's my challenge to you all (developers and users alike, I hope I don't annoy too many people by cross-posting this): come up with a name, in retrospect, for the skin which didn't need a name until MediaWiki 1.3, because it was just "standard".
How about "Simple".

Ah, but isn't "nostalgia" even simpler? Perhaps something more descriptive; I was going to suggest "ochre", but there's no more or less off-yellow in it than some of the other skins, really, now I look....
