How auto subscribe to group?
How define that when one user create document, then auto subscribe on notifications for it not only user who created, but also to all user from some group?
For example model have user group
USERS. We create three users that assign to this group:
USER3. And create one user
USER4 that not from this group. When
USER1 create new document from model, then to this document auto subscribed
USER3 because they from group
USERS. When document create
USER4, then again auto subscribed
USER3 to second document.
What right way define such autosubscribing for group?
