If you want to annotate privately with a group of hypothes.is users, then our groups feature is what you”ll want to use. Once you create a group, you can invite others to join it by sharing a special link. That link will also serve as the group home page with a list of members and texts annotated by the group. You can also link to a stream of annotations created by group members from the group home page.
NOTE: after linking to documents to be annotated form the group home page, users must 1) activate hypothes.is and 2) toggle the scope selector in the hypothes.is sidebar to the appropriate group from “public.”
