This module finds all plaintext emails and email links from the content and replaces them with span elements. All the addresses are stored in 64 base encoded srings to JavaScript array in souce code. Then on client side browser finds emo_email span elements, replaces and encodes them back to email addresses.

All emails inside form elements are left untouched. Same as anchor texts, unless it's email address. You can define default text string for replaced email address in module config.

Both emo touched span and anchor elements have emo_email class name that you can use for css/js.
