How can you join a channel in Slack?

Joining a channel in Slack is primarily done by browsing the channel list or using the "Join Channel" option. This feature allows users to see the channels that are available to them and join any public channel that interests them with just a click. This action makes collaboration simple and straightforward, as users can easily explore topics and teams without needing to request access or message admins.

While sending an invitation request may be necessary for private channels, the standard way to join any channel, especially public ones, is through the channel list. Options that involve directly messaging a channel admin or creating a new channel do not provide a direct means of joining existing discussions or groups, which can be accomplished efficiently using the method highlighted in the correct answer.
