I have added a new link over on the side of my blog for the Autodesk's MEP Discussion Group.
Autodesk MEP Discussion Group Link
If you are looking for a different product than ABS/MEP, you will want to click on "All discussion groups" and it will take you back to the main area.
Getting onto this discussion group is free.
You will sometimes get Autodesk "workers" pass through with answers to your questions, but typically you will get the most feedback from other cad users like yourself.
So keep that in mind when testing out their suggestions.
If you need true help from Autodesk you will want to go through the Subscription Center and create a "ticket" with them, if you're on subscription that is.
