Every Slack workspace has a #general channel. All members (except for guests) are automatically added to #general when they join a workspace and, unlike other Slack channels, no one can leave it. This makes it a great place to share important messages, like announcements, that everyone should see.

Share what’s important

All members can see anything posted in #general, so we recommend discouraging unnecessary messages. If you're a workspace Owner or Admin, use the options below to help reinforce this.

• Restrict who can post to #general
  Workspace Owners and Admins can restrict who can post to #general by adjusting the channel posting permissions.
• Set a channel topic and purpose 
  Make it clear what the #general channel is for by setting a descriptive channel topic and purpose.
• Rename the #general channel
  Workspace Owners and Admins can rename the channel to something more descriptive, like #announcements, #notices, or #room101 — whatever suits your workspace's needs!
• Notify members of urgent announcements
  Mention @everyone in #general and ask people to react to your message so you know who’s seen it. 👀

Note: The #general channel can’t be converted into a private channel or a shared channel.

Reduce noise

Although it’s not possible to leave or delete #general, members can choose to adjust their channel notification preferences.

• Mute #general
  Members can mute activity in #general the same way they'd mute other channels.
• Ignore channel notifications 
  Members can adjust their channel notification preferences for #general and ignore any @here and @everyone notifications.
