I have created a Global Cinema 4D users group for professional and hobby users in the early 2009.
Now starting in 2016 there is a small fee of 10 euros to join the group if you are a recruiter.
If you are Cinema 4D user or a creative then joining is free.
Membership payment is only one time for a lifetime membership.
Instructions how to join
