Set who can make announcements

By default, all members have the ability to use special @mentions and the #general channel to get the attention of many members at once. Here are some ways people can make an announcement in Slack:

• Use @here to notify everyone in a channel with an active status
• Use @channel to notify all members of a channel
• Use @everyone to notify every member of your workspace
• Post a message in the #general channel where everyone is a member
