Using the following line in any HTML file (that uses EmailEncoder.js) would display
the e-mail link listed below. View the source if you don't believe me!!
<script language="Javascript">encoder.writeEmail("Dw4GOxYqHgNBPyYSEAEfFhISMgYeEjMVUDIUHhEXQxAODA==");</script>
It is definently not shorter than a straight mailto: link, but will keep those harvesters away from ya!
