Any chance of having such a sub forum here?
We will look into this and will discuss it then with all members as soon as we are ready to finetune the new forum.
Just to be fair, Nikon 1, Fuji, Canon R etc. did neither had a lens subforum for their mount at dpreview.
Be all assured, that we will involve every member as soon as there is the time for forum-restructions/ questions and we will have polls about it.
At the moment we should focus more to spread the news about DPRforum.com.
