Muting a channel
Click the bell icon in the channel header to mute (no notifications) or unmute (full notifications). Three levels via the channel settings:
Every message (default for active channels).
Only @-mentions and DMs.
Nothing (full mute).
Leaving a channel
From the channel settings dialog → Leave this channel. The channel disappears from your sidebar. You can rejoin from the directory.
Note — Area channels and DMs can't be left — area-channel membership is derived from area access, and you can't leave a 1:1 or group DM you're part of.
Archiving a channel
Channel owners, channel admins and realm admins can archive a channel. Archiving:
Removes the channel from sidebars.
Preserves the message history so admins can still browse + unarchive.
Stops any further messages from being sent.
Sole-owner handoff
If you're the sole owner of a channel and try to leave, Carerealm asks you to promote someone else first. You can't leave a channel with no owner.
