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.
