Creates an email link from the shortcode [emailme] that spam bots don’t find. 
By default it uses your wp admin email but you can specify as parameters either: 
 – ‘name’ (for the first portion of the email before the @ symbo) 
 – ‘addr’ for the full email 
 – ‘display’ for what the link should actually display in between the <a> tags.</a>
If your wp-admin panel email (check your General Setting panel) 
is: info@freedomonlineservices.net then 
Examples: [emailme] => info@freedomonlineservices.net 
 [emailme name=’dave’] => dave@freedomonlineservices.net 
 [emailme addr=’someoneelse@somewhereelse.fake’] => someoneelse@somewhereelse.fake 
 [emailme display=”info at freedomonlineservices dot net”] => info at freedomonlineservices dot net (but linked to the actual email!) 
Note you can also set the ‘display’ option to an image tag if you use single quotes.

Email Me

Creates an email link from the shortcode [emailme] that spam bots don't find. Has clever parameters for convenience...

This plugin finds email addresses in the page (anywhere in the resulting HTML, not just the post content), and munges it into a random combination of encoded characters, and outputs a snippet of JavaScript to write the munged string to the page.
