A definite possibility Eggy, althought I'm not sure about the bikeforums.net part since we're not affiliated with them. This is more of a loosely disorganized band of independent commuting shmoes so we should probably leave the bikeforums.net part off.
One suggestion and please feel free to shoot holes in it, is that I wear a backpack when I commute so the logo/slogan wouldn't be seen at all. Maybe if it was relocated to lower on the back or along the left side near the botttom?
One last thing, we may actually need to copyright HHCMF and the motto. Does anyone care to weigh in on this matter? I don't know much about it, but I do know it affords some kind of legal ownership and protection from indiscriminant use.
