SDL documentation comments and SDL community authentication

How do you add comments to the SDL documentation? I thought I'd note that you have an accessibility issue (labeling search field), as a test of that capability, but I am getting an authentication prompt that an SDL Community login did not pass. We have no end of concern from writers about things they don't understand, in SDL documentation, and in SDL Publication Manager and Web Client, that might be of interest to you. I can see the value of curating public output, and of restricting access. We also have our internal system (quite a bureaucratic one) for mediating technical support issues. But it might be of some interest to you to receive unmediated comments from people working with the interface.

For reference, this is where I thought I might put my comment.
