Hi, I would like to suggest the inclusión of the Trisquel person (theme) on the IceCat list. http://www.getpersonas.com/en-US/persona/288783 About the license, there is no other option to be uploaded to the mozilla's site, but i'm sure that if there is other place to upload it, it will change the license (or be re-licensed) in case it is needed to be added.
