To create new group login to the MSPControl and click on Groups,
or go to Organization > Organizations > Groups.
Then click Create New Group in the right.
Type in the Display Name and click Create Group.
Hooray! Now you can set a location for a group, add members, and also make a note for this new group.
As usually, Save Changes will redirect you to the list of all groups, and Save Changes and Exit will leave you at the same page.
