# Organization Settings There are a number of settings for Organizations which can be viewed on this page. Note that customers should contact [support@trialgrid.com](mailto:support%40trialgrid.com) to modify these settings. [Settings TrialGrid Ltd support sets for you](../administrator_guide/organization_settings.html.md#admin-guide-organization-settings) explains what each one does. | Name | Description | | --- | --- | | Domains | List of internet domain names (e.g. example.com, example.net) which this organization owns and controls. This can be useful for determining what organization a user should belong to via their email address (see [Notes on Users, Domains and Organizations](domains_and_user_organizations.html.md#domains-and-user-organizations)). It can also be used to limit the domains that TrialGrid will send emails to on users behalf (e.g. from [Action Operations](../urls/actions/operations.html.md#action-operations)). |
