# Adding/inviting users under same TCP organization
Only an Administrator can invite other users (colleagues) to the same TCP organization.
* Click on *Organization* *Users* and then on *INVITE USER*.
* Click on *INVITE*.
Enter the new user's email address and click on *INVITE*.
An invitation email is sent to the user. The user has to confirm/authorize their email address and register in TCP. This procedure is the same as described in the section Getting Started/[Create account in TCP](/tcp/overview/getting-started/create-account-in-tcp.md)
* Only the administrator can invite new users (colleagues) and set their roles (USER or ADMINISTRATOR).
* Until the new user finishes the registration process, their status remains in the Pending mode.
To *REVOKE* user means to cancel the invitation.
