**Users can choose page themes**: If this setting is enabled, users can select a theme for their portfolio page. The page is displayed with this theme to other users. Thus, the institution or site theme can be overwritten.

29.

**Display remote avatars**: If allowed, users' default profile pictures will be their `Gravatar <http://gravatar.com>`_ pictures (:ref:`remote avatar <remote_avatar>`). Users will need an account with Gravatar for this to work.

30.

:index:`If you use your own avatar server <single: config.php; remoteavatarbaseurl>` to provide profile pictures for your users, you can use that instead of Gravatar for the default profile pictures. In order to do so, you need to add ``$cfg->remoteavatarbaseurl = 'http://example.com/avatar/';`` (with the correct URL to your service) to your config.php.

31.

**Users can hide real names**: If allowed, users who have set a :ref:`display name <about_me>` may choose to be searchable only by their display name and will not be found in searches by their real name. In the administration section of the site, users are always searchable by their real names. An administrator (site and institution) always sees the display name, first and last name and username.

32.

**Never display usernames**: :index:`If set <single: User settings; Never display usernames>` to "Yes", ordinary users cannot search for others using their username in "Search users" on the :ref:`Dashboard <dashboard>` or via :ref:`Find friends <find_friends>`. They will also not be able to see the username of any other user. These restrictions do not apply to staff and administrators. Additionally, Clean URLs (if activated) for profile pages will be generated using display names (if provided) or real names, rather than usernames.

33.

**Show users in public search**: If allowed, :index:`usernames can appear in public search results <Administration; Show users in public search>`. In addition, this feature needs to have the `value <single: config.php; publicsearchallowed>` ``$cfg->publicsearchallowed = true;`` set in your config.php file and requires a search plugin that allows public search, e.g. Elasticsearch.

34.

When you change this setting, you need to re-index the search index for the change to take effect.

35.

**Anonymous comments**: :index:`If allowed <single: Feedback; Anonymous feedback>`, logged-out users / users without a login can leave comments on public pages or pages they can access via a secret URL.

36.

**Profile access for all registered users**: If this option is set to "No", profile pages are initially viewable by all registered users, but the owner is allowed to restrict access to their institution only if they wish. Enable this option if you want to make sure all users can see each others' profile pages. Profiles of institution members will always be visible to other members of the same institution.

37.

**Staff report access**: :index:`If <single:Configure site; Staff report access>` set to "Yes", institution staff will have :ref:`access to the reports page for users in their institutions <user_reports>`. This page is normally restricted to administrators and lists extra user information including page access lists.
