With the team edition, you can share pins with all verified users, track their physical location thru device tracking on their phone, and see all updates that they make to your pins and their own. You can also include managers/set access rights on teams to allow some team members to share/edit/export delete pins as they please.
You can sign up for the team edition by clicking the team tab once you are logged into the web platform. After subscribing a team, you will have the ability to add anyone you like to the team. The members you invite will receive an email to verify that they are signed up and a part of your team.
