I'm pretty sure most Sheldon readers know this already from Paul and Scott's blog posts, but in case you read Sheldon online and you're not sure where it went, it's right here: www.sheldoncomics.com.

Sounds like comics.com kinda screwed him over by not allowing him to tell his readers where the strip was moving to.
Which just goes to show you, webcomics are the way to go! Or something...

Happy reading!!
