There are two major sections on each profile: your personal profile information and hub-related information. An overview of all of this information can be seen in the 'Profile' tab on your profile.
Personal profile information includes any relevant information to a member, including their name, email(not visible) education, job, other links, and about. This information is generally available to other members in the same hub.
Hub-related information includes the different hubs a member is in and their roles in these hubs. This basic information is also available to other members. In the 'Hub' tab, there is a more detailed overview only available to admins and members on their own profiles.
