I spoke with someone yesterday who had done it. He said it was interesting. The job is to help TT users with the program. The job is not to offer tax advice. One of the stories was to figure out what the user did wrong to get where they are (answered yes to some question that should have been no) and how to correct that. 

I know it is not for me, but if the hourly rate looks okay to you, give it a try. Report back if you do it.
