How to join the Thiel Owner's group?

I may be not understanding what you are asking.  But assuming you are referring to the Thiel thread here, it is not a group you sign up to join.  You just post to the thread as with any other thread.

OK reading through the forums, I just saw several people quote the Thiel Owner's Group, and thought it was something separate. Thanks for the reply. 

Try searching that name on Facebook.   Quite likely hosted there.  Cheers. 

Here's one and there is another @ AVSforum.com.
