Syllabus blurb on instructor availability

Instructor availability: Please note that I do not typically check email or Slack messages during the hours of 6pm and 6am on weekdays, and I do not check these at all on the weekends in order to devote time to family, rest, and religious observances. Messages received during these times will receive attention once I am back online. Otherwise you can expect to receive a response to your message within 6 hours, often much sooner. If you post questions to Slack, you are likely to receive responses faster.
