How to Avoid Turning into "Ketchup Trousers"

Here's a great cautionary article from Fortune Magazine about the perils of email, and how to avoid some of them. There are several unfortunate tales in the article, including one about an executive who demanded his secretary pay his small dry cleaning bill because she spilled ketchup on his pants. She forwarded the email, and he got a new nickname. Remember that your email is out of your control once you hit the "send" button, and don't put anything in email that you would not be comfortable wearing on a sandwich board. The article also talks about how new software can analyze volumes of email looking not just for obvious key words like "insider trading" but also less obvious signs of a problem, like late night mail, purposefully ambiguous wording ("that thing we talked about"), and signs of anxiousness.
