The makers of Avatar and other SL/OS related products have started a instituted a trouble ticket system for support. No other support is offered or provided. The time being consumed by answering questions was too much. They had to do something.
So, you can get most questions answered in-world in the Blender-Avastar group. It is free to join and enough users are around to answer questions most of the time. Plus various other groups like Builders Brewery and others answer questions and provide classes.
On the Machinimatrix.org site questions will only ne answered if you file a trouble ticket. No more impromptu help. See: New Ticket System available.
