# Adding collaborators

You may add other public officers as an **Editor** or **Viewer** to your map. They do not need to have used Maps before — they receive an invitation email and gain access when they log in.

Click on the **Settings** icon on the navigation bar on the left and scroll to **Manage members**.

Enter the collaborator's email address and assign them either a **Viewer** or **Editor** role. Any gov.sg email address is eligible (for example, `officer@moe.gov.sg`). Email addresses on approved non-gov.sg domains, as well as individually approved addresses, are also eligible. Other addresses are rejected with the error `Only .gov.sg and approved email addresses can be added`.

Ownership of the map cannot be transferred to another user.
