the quake avatar was cool, this is not just uncool but unnecessarly provocating. (e.g. this symbol is forbidden in my country, such as the communist symbols and so on.)
i don't think it's a nice way to represent our community.
here at the company i use the forums almost all day long while working, and anyone who passes trough behind me has to stare at this symbol, inculding clients.
but keep it in this selfish way, you're in power to do that.
plus, I'm a homosexual jewish black guy raised by gypsies and i find the sign annoying personally.
EDIT: now our forum has nearly 2500 nazi swastikas. congratulations.
