It is with great pleasure that I can announce that http://themes.rockbox.org/
has finally been (re)launched. This means that you can once again find themes in one easy to navigate place. The newly released Rockbox Utility 1.2 will also install themes from themes.rockbox.org.
Unfortunately, the site is pretty much empty at this point, so we need theme authors to upload their creations. If you've created a theme, please waste no time in hurrying over there to upload it.
Take care about licensing though - all themes on the site must
be licensed under the Creative Commons Attribution-Share Alike 3.0 Unported
license. If you have used the works of another artist, his work needs to be under a compatible license.
At the same time, I'm happy to announce that the themes Cabbiev2, iAmp, Engineer2, Boxes, DancePuffDuo, iCatcher, UniCatcher, ipodVOL, Rockboxed and progressive that are currently bundled with Rockbox have been relicensed to CC-BY-SA 3.0, so derivatives of these themes can be uploaded to the theme site. A big thank you to all the contributors who have given their OK to this.
Edit: Added Rockboxed to the list of relicensed themes.
