Out of sync Remember that everyone studies at a different rate. This is especially true of distance education students. Therefore be tolerant of people posting messages about topics you have already studied. Use your knowledge to help them. Remember your manners Never send a posting in the heat of the moment.
Criticism is always harsher when written.
Read your message to yourself before you send it, and remember your humour may be misinterpreted and read as an insult to others. Remember everyone's understanding of computers is different and for many people English is their second language. If after a few days you still haven't heard anything, or the message is particularly urgent, then try contacting them in person. Don't post commercial material to newsgroups, forums or listservs.
