Simos Xenitellis has been working on the localisation of free and open-source software to the Greek lanugage for the last ten years. He started with the translation to Greek of the graphical user-interface called GNOME, and since then he has been involved with the localisation of other significant open-source projects. Now he is involved in the quality assurance of GNOME and the Ubuntu Linux distribution for the Greek language, and the improved language support in general in open-source software. Simos Xenitellis is a member of the GNOME Foundation. He maintains the blogs http://simos.info/blog and http://blogs.gnome.org/simos/, and suggests to visit often the Greek open-source planet, http://planet.ellak.gr/
