Possible to leave comments on SDL Knowledge Center 2016 documentation?

Hi,

 When reading the SDL KCCM 2016 documentation, it would be great to be able to leave comments. Is it possible to get that kind of account? I tried logging in with my SDL Community account, but that did not work.

And I mean comments on the actual content of the help pages, i will post any questions I have in this forum.

Best regards, 

Joakim
