If you can't make it to class, mention it in this thread the morning before class time or one day ahead. Tell us which class you will miss and why you can't make it. If you are going on a conference trip, you need to notify me at least 10 days ahead of time.

OK, no problem. We'll cancel the class on April 25th and reschedule it later if needed.
