Send mail in preference to posting a followup. Read all available postings on a subject before posting. Or send email. That is a true stupid waste of bandwidth and disk space. If you are serious about email replies, include a signature.
Mail can be flakey.
Do not assume that your mail system is the only one in the world. The world does not work that way. Ask an experienced poster by mail about a subject. But, don't take the news too seriously, but remember in the real backcountry, you are playing with lives. This wisdom is the product of such loss.
