Roy, you can see David's comments above. Be happier and ask the local users what they want to learn about. I knew of 3 users. Someone in Rockwell, married to a framer, therefore a structual expert. A stewardess in Fort Worth who was doing images for people. A building official from Kentucky who was drawing for $.25 and picking up plenty of clients from Craigs List.
I am using Chief 6, and it is fine. Better 3d than before.
Like you I am busy, because I lost all my employees in the crash of 2008, so I have enough business for the few of us left.
If you get a group together, I would be interested in attending your meeting.
