# Adding or Removing a Collaborator from a Project
This article explains how to add and remove collaborators in your project. Adding collaborators means adding workgroups, streamlining access, and promoting controlled collaboration. For more information on collaborators, see [What is a Collaborator?](/collaborators/what-is-a-collaborator.md)
{% hint style="info" %}
NOTE: You must be a Workgroup Administrator to complete these tasks.

## Adding a Collaborator
{% stepper %}
{% step %}
### Open the Collaborator page.
Open a project by selecting it from the main project screen.
Select **Collaborators** menu item from the left-hand menu of the main screen.
{% endstep %}
{% step %}
### Add a new collaborator
Select the **Add Collaborator** button in the top right corner of the screen.
{% endstep %}
{% step %}
### Find and add your collaborator to your project.
Search or scroll through the list of potential **Collaborators** until you find the collaborator(s) you would like to add to your project. In the **Add Collaborator** screen, select the checkbox next to their name.
When you have finished selecting all your Collaborators, scroll to the bottom of screen. Check the box **I approve inviting selected collaborators to this project.**
Press the button **Add Collaborator** to initiate the collaboration invitation process, in which both parties will need to accept the collaboration on the project.
When you add a collaborator to a project, you're essentially adding their entire workgroup. The Lead of the collaborator's workgroup receives an invitation email. To gain access to the project, the workgroup Lead must approve the project's permissions policy. To learn more, see the [information about the project's permission's policy.](/projects/creating-a-new-project.md)
{% endstep %}
{% endstepper %}
## Responding to the Collaboration Request
If you've been invited as a collaborator, you will receive an email about the collaboration request.
Also, every Workgroup Admin that was selected for collaboration, will receive an email inviting them to collaborate on the project. The email instructs each potential collaborator to open the project in the Rhino FCP and review the project's permissions.
## Viewing and Accepting the Project Permissions Policy in a Potential Collaboration
After the prospective collaborator clicks the link in the email, the FCP dashboard is where the new Project will appear. The collaborator selects the project, then is taken to a screen that shows the Collaborating Project's Permissions Policy. To accept, the collaborator clicks the **Accept** button. For more information about the permissions policies see [Persona and Permissions Policies Reference](/projects/persona-and-permissions-policies-reference.md).
Upon accepting the permission policy defined for the Project, the collaborator can see other parts of the project. You will also see your own site and your collaborators on the Collaborator's page.
### Removing a Collaborator
These steps apply to data schemas, datasets, code objects, and code runs. To delete a version of these things, make sure you are on the page that contains the original object with the version you would like to delete. If you need to search for data schemas, code objects, or code runs, use the text boxes located at the top right corner of the page. To search by name enter the full name or part of the name in the Search Name text box. To search by description, enter part of the description in the Search Description text box.
In the box where your original object is, there is a row for each version. Navigate to the version you want to delete and select the three-dot menu button, shown here below:
The menu button is on the right-hand side of the row. Click it to view a new menu. The new menu should have an option to remove that object's version, click on that to delete the object's version. To completely remove an object repeat the process to delete all versions, once the last version has been deleted the object will be deleted.
In the case of a project or a collaborator, there is no concept of a version so you will just navigate to the object and then select the three-dot menu button and choose the remove button from the menu.
