Ability to communicate with group owners on demand
Ability to trigger some workflows to communicate with group owners – for example, contact them by email to ask questions about their groups (other than to entrust them).
Use case 1: Unused group, owner gets the email and decides to keep it – but it is really old and unused, so before admin taking action on it and overriding the owner’s decision, he would want to contact him and find out why.
Use case 2: Unused group that has about nothing in it and/or no members. IT admin would like to contact owners to ask them if it's ok to delete the group instead of entrusting them to archive it by themselves.
