Do not start a new thread. Simply reply to my posting.
Be sure to comment on at least two of your classmates' postings. Your response should be at least 5 sentences long. This includes responses to classmates' posts. Your replies must be more than a simple phrase like "I agree" or "I like your answers". Replies should reflect why you agree or like what has been posted. Your replies must reflect a genuine effort to engage your fellow classmates regarding the comments provided or the problem that has been solved. Please think about the questions and your peers' responses and reply thoughtfully and courteously, according to netiquette rules. Use good English grammar, correct punctuation, and complete sentences. While the posts will mostly be judged by their thoughtfulness and completeness, I reserve the right to take off points for grammatical errors, especially if they interfere with the clarity of your post.
Your initial posting is due on Monday by 11:59 pm CST. Your responses to 2 of your classmates are due on Saturday by 11:59 pm CST.
