Hi Genna

I tried using the individual wiki for adding but then you lose access to the template file for the course. If you use collaborative mode then other users will see your changes to the wiki page.  

My idea is to create a collaborative wiki for the course content and  the learner can copy the content to their individual wiki so they can make comments there.

The permissions for the collaborative wiki for the learner role can be adjusted so the learners are not able to change the content. To change the permissions select the collaborative wiki > Wiki administration > Permissions and take off the learner role for Save wiki pages, Add comments to pages and Create new wiki pages.

Once the content has been copied by the learners and pasted into their individual wiki then  comments can be put beside the content

Regards
