// Email Linkify v0.2
// Updated by Daniel W. Crompton <daniel.crompton@gmail.com>
// Made By Jason (aka GamingFox)
// Last updated: 6/4/05
//
// This adds the mail address to the LinkedIn addressbook for
// later addition.
//
// This script is made according to a request:
// Have you considered "linkifying" email addresses that aren't 
// linked with mailtos? Much to my surprise, nobody seems to have 
// done this yet, and I would find that very valuable.
//
// The regular expression of an email address was found at
// http://www.regexlib.com/REDetails.aspx?regexp_id=284
// Thank Myle Ott for the regular expression.
//
// The script follows same concept as the Linkify script from
// http://youngpup.net/userscripts. This time, its for email
// addresses instead of URLs.
