We have created a new forum on TechNet specifically for MDT-related questions – no question is too simple or too advanced.  You can access the forum via http://social.technet.microsoft.com/Forums/en-US/mdt/threads.  It’s been around for a couple of months, but we haven’t publicized it too heavily so we could slowly ramp up.

As always, I seem to be keeping too busy to spent a lot of time responding to questions on the forum, but fortunately there are several other experts (including Tim Mintner, Keith Garner, and Johan Arwidmark) who have been helping out with that.
