To share topics or collections with team members, they need to be in folders that you assign them to.
Once you added team members to your account, you can begin sharing topics or collections with them by adding topics to folders, and then assigning team members to these folders.
Begin by accessing the team settings screen by clicking on the account name, and then "Team Members".
Once you have accessed the Team Members screen (which you can access directly by going to https://my.upcontent.com/team-members) you can assign a team member by finding the appropriate one and and clicking "edit" under the "Assignments" header.
From here, select from the drop down menu which folder you would like to assign them to, as well as the permission level you would like them to have before clicking "Assign Folder" to finish the process.
Repeat the process to assign multiple folders to the same team member(s).
