When a project owner creates an invitation, the recipient can accept it in two ways:
Invitations are sent via email. If the recipient of the invitation already has a LEANSTACK account they'll be encourated to sign in. If not, they will need to use the invitation to create a new account. This process will also automatically add them to project.
If the recipient is already signed into LEANSTACK they will also see a notification there. They can click on the notification icon, review the invitation, and either accept or decline it.
The sender of the invitation will receive an email once the invitation has been accepted.
