Email or IM's can come back to haunt you
Remember that any email or instant message you send could come back to haunt you.
Once you send an e-mail, it has a very good chance of being saved in someone's mailbox or archived on a server forever. People involved in scandals like Oliver North, Monica Lewinsky, Patricia Dunn (the former Hewlett-Packard chairman), and Bill Gates probably wish they could take back an email or two... Instant Messages can also be saved and used at a later date to embarrass you. Paris Hilton might be able to shed additional light on that subject. Be careful about what you put in writing and whom you send it to.
