Steve:
Never had a badge or plate indicating I was a Dark Sider! There are probably a few sites which have them available. Not sure as I've personally never did a search. Some folks, although Dark Siders, like to remain anonymous! They like to avoid the "bashing" by the nay- sayers/critics. If someone would come up with a sticker/badge specifically for "F6B Dark Sider" it my get wider interest
Regards
