Other than group officals, can other members of a group see my personal details help in the membership?
No, a member can only see and update their own details using their own username and password. Group officials can be given special usernames and passwords by the administrator that enables them to input, update and view member details. The group needs to decide want details will be held on the membership system, who should be able to see the details and who should be able to update the details.
