Benjamin Peter reports:
“Debian is calling for your help to bring a more user and game friendly image to debian and ubuntu by organizing a games screenshot party.
What is this?” You are asking?
Well, see the announcement on debian-devel-games:
“The main theme of the party will be Screenshots; making sure that all game packages which should reasonably have a screenshot, has one.
Of course, this is only a theme, and if you want to work on any other
aspect of the games packages, feel free to do so, and join the party!” ”
Seems to be a perfect spot for a linuX-gamer to help 
Thanks Ben for this hint.
