But it looks like everyone who purchased something in the first months of 2008 didn't get the link to the free wallpapers. Which is a total bummer.
Anyway, I just now fixed the link hiccup... So if you were one of those folks that made a purchase but didn't get a free wallpaper, just send me an e-mail from the address used in your Sheldon purchase...and I'll send you the wallpaper link! Thanks!
