Oh. That's not what you were asking. I should read ALL of a post before replying, I suppose.

The official word is that since they are writing Robotman out of the script, they changed the name of the strip to Monty because it's about him now.

Whether or not the email change has anything to do with this, I don't know. I'd guess he didn't want to get a bunch of hate mail from Robotman fans, and took himself offline temporarily to avoid dealing with it.
