I was on the Making Fiends website today and I saw it said that Nick is gonna start selling Making Fiends merchandise.
Perhaps it means new episodes are on the way soon. They wouldn't have 6 episodes of a show, sell stuff, then be done with it. I haven't gotten anything from the Fiend list yet though. www.makingfiends.com for those who wanna see it for themselves and are too lazy to type all that in the address bar.
