United Media, being the profit-driven, soulless corporation that they are, refuses to post a notice on Sheldon's comics.com website to let the readers know that the comic is moving, and actually edited out a notice that Dave put in the comic itself. Of course, they don't give a crap whether the readers know where the comic is once it leaves their site. Not like that's going to be making them any money.
So it's up to us who read the comic to get the word out about the move. http://www.sheldoncomics.com is active, currently pointing to the comics.com website, but will point at the new site starting tomorrow. Change your bookmarks today, and pass the word along!
