General rule: the larger & busier the channel, the more people should use threads to keep conversations organized.
Always: responding to announcement posts in read-only channels
Always: responding to questions in help/discussion channels
How do I encourage students to collaborate & ask questions in channels, as opposed to direct messaging/emailing me?
Set proper expectations & etiquette at the start of the course that students should default all questions to channel so that everyone can learn.
Address instances of poor etiquette; take the opportunity to quickly and empathetically educate
Socialize your availability (Slack can even auto-update your status with the Google Calendar or Outlook Calendar integration).
Where can I go for further support with Slack?
