Manuele Carlini created a really nice document, in which he wrote down his proposal for design guidelines.
Do not use the Harabara font! It is not licensed, not even for non-commercial usage. If someone feels like asking the author to license it to us, this would be great! http://www.dafont.com/de/harabara.font Update: We are allowed to use the DEMO version for non-profit stuff. |
Generally, feel free to follow the Open design proposal and make your own decisions.
