ReaderExtensions / Watched Folders / enableComments newbie question

Hi there,

I am currently using the Live Cycles ES Preview, while I wait for the full version to finish going through your licensing process. Here is my over-all goal:

I would like to set up a watched folder that takes PDFs dropped into the input folder, enables comments, and saves the new files to the output folder.

Ive figured out how your folder watching works (very cool!) but not how to get a service to turn on the comments.

I see that the ReaderExtensions service has an enableComments usage right associated with it. But I cant set up a watched folder end point in it via adminui.

Do I have to workbench something? Wheres a good starting point for figuring out how to do that?

Thanks,
Phil
