We have plenty of link buttons, but none yet that we can use as a nice banner of standard size. This has been requested several times, especially by the Spanish-speaking GNU/Linux community. So if anyone has a proposal, please make yourself known… We’re looking for something simple, understandable by anyone (geek humor prohibited!), and if possible that would insist on freedom.
This is also the opportunity to present our latest “liberated by GNU/Linux” button, a derivative of the Ubuntu version created by Pavel Rojtberg who licensed his work under a CC by-nc-sa license. If you can translate the text to Spanish (Castillian) or Catalan, please leave a note down here, so that we can publish it under these languages as well.
EDIT:
The French and the German versions of the new button have been added. The source file of the button is available together with the other button files on the button page.

Please provide the source code. (or didn’t you use the SVG Pavel provided ?)
Translations:
DE: Befreit von GNU/Linux // Windows Vista entlassen
Thanks, Thomas.
I’ve added the source file (SVG indeed) in the compressed file containing all of the button sources there.
The German version is now online.
