To invite or add users to a project visit the “Projects” page and hover over a project and click “Share”.
Alternatively you can visit the project “Settings” page and click “Add more users” in the “Manage users” section. You can find the settings page by visiting your project page and clicking on the “Gear” icon next to your project’s name.
Once on the “Invite users to the project” page you can either click on users that are on your team or that you’ve worked with in the past. We call these users “Common users”. Or you can send an email invite by scrolling down to “Share with new collaborators” and entering their email address. To finalize what you have entered in the text box press your enter key. Once they are added they will now be able create and view tasks on your projects website!
