I was lucky to have a scanner courtesy of Tigerfire at CF this year, and managed to scan the badges I finished in the dealers den. I'm so pleased that I didn't have to take anything home to finish!
My favourite one is Puzzle's badge, because it's based on the Crystal Maze! Awesome!
Usernames I can remember: Blackstud88, Blackdragon1 (of the Spanish Trio), Hozziehossbourne/superswede, Puzzle, and Speed for Ssejhammer
