**  EmailLink script by Jason Johnston (jj@lojjic.net)
**  Created August 2003.  Use freely, but give me credit.
**
**  This script will allow you to obfuscate email addresses
**  in web pages so spam harvesters will not see them.  The
**  email address is entered in plain text with abnormal
**  characters, and the script decodes and creates a 
**  mailto: link from it. See EmailLink-doc.html for details.
