Making Default Channels
Sometimes it makes sense to automatically add new team members to a particular Channel (for example, an "Announcements" channel for posting company-wide bulletins).
- Visit the Channel,
- Click Settings in the right-hand sidebar, and
- Toggle on the Auto-subscribe new members to this channel setting.
Be careful not to overuse this feature. In most cases, people should opt-in to the Channels they wish to follow.
