Really nice feedback thanks everyone. I thought it would be cool to have a Smurf site where people who aren't too tech savvy, or don't want to pay hosting fees, etc etc can record their collections. I don't mind looking after the site so that's cool. Between the forum here, existing fan sites, and the collections site... the Smurf community should be set!
I must confess to being a matchbox fan too. I thought as people often have multiple things they collect, it would be good to have one userID, but multiple collections. I have smurfs, matchbox cars, and Pink Floyd!
