Allowing your community to create groups can be quite tricky at times and keeping track of what groups were created and when might be proven difficult. Not anymore, though. All of your administrators can be now notified when a new group gets created. Simply navigate to WP Admin -> PeepSo -> Configuration -> Groups
In Advanced panel find E-mail Admins when a new group is created option and set it to Yes.
All admins will be notified by email when a group gets created.
