Re: OMG Laser Shotgun

Yea i know each member owns the forum, some more than others... Reminds me why i quit a job in Germany, not that you wont find disagreeables everywhere, just their culture has their noses up everyone elses back side far more than most.... that said, America has their own idiocies too, my problem is disliking any critism and saying so!
