And just because somebody puts up a Web site about cancer doesn't mean she's an oncologist. Before quoting anything or anybody on the Net, make sure the person or site is a reputable source. If you're going to quote from a page, make sure you know who put the information up. Also, be careful what you write in your E-mail and in your contributions to mailing lists and newsgroups. Remember, such communication can come back to haunt you later on, either in court or in some other embarrassing situation.
Nothing ever disappears from the Internet.
