The navigation bar at the top of any Stream page makes it easy for you to browse videos, channel or groups, create new content or easily search for content. You can also use it to invite coworkers, access help or provide your feedback to Microsoft using the small icons on the left.

Invite coworkers
Microsoft Stream really shines when your colleagues are also using it. Invite your coworkers from the navigation bar or by clicking the notification. By inviting them, you enable them to view the videos you have already uploaded and give them a chance to upload their videos and share with you. For more information, see Invite co-workers.
Learn to use Microsoft Stream
Directly from the home page, use the tutorial videos. These videos cover the most common actions in Microsoft Stream and make it easy for you to get started. After you're familiar with Stream, to hide these videos, select Don't show this again.
My watchlist
This section only shows if you have videos in your watchlist. A watchlist is a convenient way to bookmark videos that you want to come back to. These could be videos you really want to see but don't have the time at that moment or videos you want to watch again. From any video, click Add to watchlist. To learn how to manage your watchlist, see Manage your watchlist.
Followed channels
Channels are a great way to organize content. To stay in touch with new videos added to a channel or to bookmark it you can easily follow a channel. If you are following a channel, this part of the home page lets you see the new videos added to a channel and/or find the channel you follow easily. If you are no longer interested in a channel, to unfollow it, click Following.
For more information, see Follow a channel.
Trending videos and popular channels
At the bottom of the Home page, you will see some more Trending videos, and also, Popular channels. Trending videos are determined by the number of views, likes, and comments. They're a convenient way to keep in touch with what's really popular in your organization. Popular channels highlight channels that are getting attention.
