To invite a collaborator to your project, do the following:
In your project in Hederis, go to the Settings & Invites tab.
In the “Add Collaborators” box, type or paste the email address of the person you want to invite.
Click “Send Invite”.
An email will be sent to your collaborator inviting them to join your project. (If they don’t see the email, have them check their Spam folder.) You can also copy the invitation link from that Project Collaborators menu and send that link to them directly.
