Only the owner of the project or the notebook can share it with other users and groups. 

1. Select the green “Share This Project" or "Share This Notebook" icon at the bottom of the project page or the notebook page. This will open the share dialog box.

2. Select the groups or individuals who you want to have access to the project or the notebook. You may select as many as you would like at a time but they will all have the same level of access. If you wish to grant different levels of access (e.g. one group has only write access while another has both write and view access), then it is recommended to share them separately.

3. Select the level of access you want the individual or group to have. View/Read access will allow a user to see the content but not add content. Write/Create access will allow a user to add content to a project but not see any content they did not add. If you wish a user to both see and add content to a project you must select both options.

4. Select Share to send invitations to selected parties. They will need to accept the share invitation sent to them to begin writing/view the project or the notebook.
