Discalaimers – you know that paragraph or two of legalese you get at the foot of emails emanating from big companies (“Nothing in this email shall be construed blah blah…..”) – can become quite ridiculously large. An 1100-word example was recently spotted.
Writer Wendy Grossman has therefore come up with an Anti-Disclaimer, which you are free to copy, use, adapt and distribute:

IMPORTANT – ANTI-DISCLAIMER – This email is not and cannot, by its nature, be confidential. En route from me to you, it will pass across the public Internet, easily readable by any number of system administrators along the way. If you have received this message by mistake, it would be ridiculous for me to tell you not to read it or copy to anyone else, because, let’s face it, if it’s a message revealing confidential information or that could embarrass me intensely, that’s precisely what you’ll do. Who wouldn’t? Likewise, it is superfluous for me to claim copyright in the contents, because I own that anyway, even if you print out a hard copy or disseminate this message all over the known universe. I don’t know why so many corporate mail servers feel impelled to attach a disclaimer to the bottom of every email message saying otherwise. If you don’t know either, why not email your corporate lawyers and system administrators and ask them why they insist on contributing so much to the waste of bandwidth?
