  3. Select your group from the list of groups that appear in the center of your page.
  4. Select the gear icon in the upper right corner.
  5. Select Group Settings.
  6. Select Permissions, then Basic Permissions from the menu on the left.
  7. Next to "Allow members external to this organization", check the box which reads "Allow new users not in".
  8. Select Save. You can now add non-PSU email addresses ( to the group membership.

Further Resources

A group can also be part of another group. For more information about nested groups, view the Google topic Add a group to another group.

There is no limit to number of members a group can have. However, Google has strict policies on spam and in public groups they limit the number of addresses that can be added at a time, to prevent the possibility of spam groups.
