The Browse view of your channel allows visitors to your channel to see, by default, the customized content (channel trailer, sections) you are displaying. Disabling the browse view will display your channel feed to all users. You can enable and disable the Browse view of your channel in the channel navigation screen. You can get to the channel navigation screen by clicking on the arrow that appears when you hover over your channel name and click Edit channel navigation. In channel navigation you can also determine which activities appear in your feed, and update the settings for your discussion tab. Hope this helps!
