iWeb. Hmm. Anyone remember iWeb?
Oh yeah. It was discontinued by Apple along with MobileMe in June 2012. MobileMe was the only place Apple supported it, back when it was a part of iLife '09. Huh.
Well, I hear there are ways to pull the code and resources out of iWeb created pages. Then you could maybe use these templates on websites other than MobileMe. But don't ask me how. Perhaps the developer of Themes Box can help us out.
