Plugin Name: Email Encryption
Plugin URI: http://www.fel.li/2006/10/18/email-encryption-in-wordpress/
Description: This plugin add an easy encryption to email addresses, so that spam bots do not recognize them anymore. The encryption is done by translating each character of the email address into a corresponding ASCII number, add 3 to that number and convert them back into a character. By doing so, the email address looses its typical format.
