I got a phone call from a Mudcatter last night. He said Mudcat was down Monday and Tuesday mornings. I was gone Monday, but I noticed Tuesday that at about noon Mudcat time (9 AM my time), Mudcat had a "placed offline by operator" message off and on.
Today, I notice that Mudcat is very slow at times.

I e-mailed Max, and he said that Mudcat has been slow or offline because he has been fixing and tweaking things. This process will continue over the next couple of weeks, so don't worry about it.
