Post at least three additional messages during our academic week in our weekly discussion board. These three additional messages need to be robust, typically at least one solid paragraph each. Also, they need to be in discussion threads other than your own main posting. Yes, of course, you can reply to people who are discussing your own main posting. Yes, of course, you can have short replies which are less$-$than$-$robust. Those types of replies are wonderful! Nevertheless, the minimum standard for additional messages for grading purposes is to contribute at least three additional messages to the discussion threads of your classmates. Yep, you probably will have more than three additional messages during the week, but make sure that at least three of them are robust and also are in discussion threads other than your own. Contribute at least three additional postings in discussion threads other than your own thread before the end of our academic week, which is Sunday night at $11$:$59$ pm Central time.
