The bold tells you that there is new activity in that channel that you have not yet read. When you look at your workspace, you see that some of the channels listed in the sidebar are bold, and others are not. Once you’ve joined a channel, you can read all the messages that have been posted in that channel. You can also browse channel names by clicking the Channel Browser in the list of shortcuts in the Slack sidebar above the list of channels.

Click the name of a specific channel to join it.

You can see all the public channels in your workspace by clicking on the word Channels in the side bar (as in the image). Except for default channels, you must take an action to add a channel. There are a few channels that are “default channels,” which everyone who joins the workspace automatically becomes a member of. A list of channels always appears on the left side of your screen.Ĭhannels can either be Public - open to everyone on the workspace - or Private (you join only by invitation).
