Tabs are located at the top of your channel and by default, come with a few useful tabs already set up. The Conversations tab lets you view a history of your team’s discussions. You can reply to any discussion, or send a message to everyone on the team. The Files tab takes you to all of your team’s files. The Wiki tab lets you post free-form content. This content might include meeting notes, draft documents or photos and videos.
