Hey I've got a few questions for you veteran skinners here..

First off, I'd like to add a rollup button to a skin. It's a pretty easy task most of the time, but I'm working with a transparent skin, and I can't figure out how to add buttons to transparent windows. And secondly, the skin I'm working on is not so much my own, but more a modification of "Arrow". I think it turned out well, and I'd like it to be available for others to download, but I dont want to gain any points for downloads, etc, because it's still 80% someone else's work! Should I just keep it to myself?
