At least Enrico Troeger and Borja Schwember should be mentioned as well under the German translations team, see http://i18n.xfce.org/wiki/team_de#uebersetzer . I  don't really know how far the other ones mentioned there were involved in translating -- you might want to contact them.

Thanks for your efforts,

Fabian
