You can create teams now, A few things you want to notice is Group type. I suggest keeping the group to "Closed." (Set by default) this will allow ONLY your team members to view your team's personal forums. Once the team is created, There is a gear, click on that and under Group Setting > Update Privacy. You want to set "Membership Approval" to "Any requests to join must be approved by a moderator." otherwise anyone can join with out verification. There are some styling fixes I need to change.
