Hello!
I've been pretty inactive here, but I check the forums weekly.
I will happily permissively license the WPS. I'm kinda jazzed actually that it's being used; I just threw it together on a request. It's still in the Wiki here:
http://www.rockbox.org/twiki/bin/view/Main/WpsIpod5gGraveyard#Car_v1_0 and feel free to use it, with the caveat that it may not work anymore. I wrote it quite a while ago.
I need to look into exactly what's needed to make it "legal" for the new site. The main reason I haven't bothered adding licensing to my themes is that I'm a very lazy person, so while I know that there's an official theme site with all these requirements and I'd love my themes up there, I can't quite get the gumption to actually put them there.
The theme I've been using for about a year wasn't even put up on the old site (The Wiki) because of this.
But I'll work on it. In the meantime don't hesitate to get it off of the Wiki link above.
UPDATE:
Yeah I just checked the theme, and it's got some issues. It still "works" but the progress bar is broken and the words don't show up on the screen the same way they used to. I'll fix it before I fully upload it, but I'm not 100% sure when I can. Hopefully during this week.
