The first step to creating your team is to create folders and move the topics and collections that you want others on the team to see into these folders.
Folders are how you control which team members have what level of access to your topics or collections.
Once you have done so, you can begin adding members to your team.
Once they have accepted their invitations, you can begin collaborating by assigning additional folders (if needed).
Your team members will then be able to access and interact with those topics or collections, and the suggestions within.
