Messages may be read and posted at any time. It is recommended that a student not wait until the last possible minute to attempt posting. Students who choose to do so should be aware that encountering computer problems when attempting to post will not be considered a legitimate excuse. Training sessions have been scheduled for those students who wish to have some practice in with newsgroups. It is important to follow certain basic rules of discussion etiquette both in the classroom and during electronic interactions.
Respectful disagreement is OK, in fact it's great.
However, respect is the key. When posting to the news group, please respond thoughtfully and considerately. Remember that real people go along with the computer ids. Rather, elaborate your point. Provide reasoned arguments and tie in your ideas with the concepts that you are learning about in the course.
