I was in the same boat as Bittereinder. I thought, wadda minute, how come I don't have that green 'K' Kickstarter badge? However, from Jito463's post, I determined that this black and red thing is for Dragon level kickstarters. As rhiggins said "... it seems with the lower tier it is more obvious that you are a kickstarter backer than higher tier backers".
If we kickstarters don't know what the black and red badge means, how would the general forum members know? I hope you are listening ForkTong.
