In Plattar each project can have its own team members. You may have some team members across all projects and you may have a team member that has access to just one project. Your team might be your business colleagues, but it could also have people outside of your business such as a 3D contractor.

To add a new person to the project enter their email
Select their permission level . See [permissions link]
Hit the Send Invite button
This will send an invite to the persons email address. The email will be from Plattar Support and titled "You have been invited to a project on Plattar". Inside the email is a button to "Sign in" which takes them to https://app.plattar.com/cms/#/project/list. The person must sign in using the same email address that received the invite email.
If the person says they did not receive the invite (likely due to their spam filters) they can still register using the email address the invitation was sent to, and they will get access to your team. See I didn't get my invite
