Pissed off at your boss? In love with that hot babe but are too afraid to disclose your feelings? Want to send a quick message to God?
That's what Zen E-mail is for! Write whatever you want! Your message shall be transmitted to the ether where only the most adept ether-readers will be able to view it.
There's no need to use an e-mail address, the "To:" field can contain watever you want -- a proper name, a nickname, whatever! So go ahead and get it off your chest.
