If you have admin privileges, you can deactivate current users or request new users by selecting "Manage Users" in the main dropdown in the upper right corner.
From here, you can click the "Request New User" button:
Or click on the grey pencil icon next to a particular user to edit their Trade Approval Status, Admin Status, or deactivate them entirely by unchecking the "Admin" box.
Please note, that for data security reasons we do not allow organizations to delete user accounts. Deactivating a user will make them unable to log into your organization's Data Center account.
If you don't have admin privileges, you can still request new users but please email HelpDesk@trgarts.com to request updates to current users.
