You can configure how users are allowed to set up their user profiles.
Letting Users Control Their Own Settings
You can let people control who sees their profile information in the community, as well as provide them with other customizations, or you can set this information for them. For example, you can enable users to change who sees their name and email address, or you can select a group of users who will see their name and email address.
Configuring User Profile Templates
User profiles, like other content, can be found on searches. Because of this, what people say about themselves — including interests and areas of expertise — can be a great source of information for people looking to have a question answered.
Selecting Fields for Hover Cards
You can decide which of the short fields from people's profiles are displayed on the cards that are shown you hover over a person's name or avatar in the community.
