Yeah. You're right. That pending mentoring match would never work.
No need to panic. You can delete a pending mentoring group prior to publishing that group. (Deleting only removes the pending match. It does not delete the users.)
To delete a pending group
- From the Admin Panel home page, click View Groups.
- Click the Pending tab.
- Select the checkbox corresponding to the group (or groups) that you would like to delete.
- Click Delete Group.
- Click Confirm when prompted.
