Forum for TR-069 discussion. Any suggestion?

I have some questions about TR-069 that probably will fit better in a TR-069 discussion forum.
So, some of you can recommend/point me some Discussion Forum about TR069 on Internet, please?

Any hint will be very helpful!
Best regards!!

I don’t know but I doubt there is one. Feel free to post here though.

Ok. Thank you! I will put some doubts here.
