You obviously have never tried to make skins for a forum. Its not that easy.
If the forums are updated, and the way skins are handled changes, it could possibly invalidate the existing skin. If you know for a fact that you intend to make more skins, you want to make sure they will work completely, and IF there are changes to the format, you want to have the changes that you made, prior to the new skin formula are all well documented.
The boards have been open a week and a day, and they don't work exactly in all broswers. First order of business is making sure they do, not creating more skins with more problems.
