All members can see a list of open teams in their organization and join as many as they'd like. Joining a team is a great way to stay on top of what's happening in that team.
When you join a team, you'll see it display in "My Teams." In addition, you'll get real-time notifications whenever somebody posts a message to the team.
1. From the Main Navigation menu, click the magnifying glass next to My Teams.
2. Search for the team you want to join, then hover to the right of the team and click JOIN.
3. That's it! The team will see a notification in Team Chat letting them know that you have joined.
