title: SharePoint publishing site email encoding/decoding
body: <p>I'm building a SharePoint (MOSS) publishing site for employee information on my company website.  I have an employee content type and am using the Contact E-Mail Address site column to store an employee's email address.  </p>
  
  <p>Want I'd like is the ability to encode email addresses at runtime to prevent the real email address from being harvested by spammers.  This would be decoded when a user clicks the email hyperlink e.g. the following HTML would be sent to the browser: </p>
  
  <pre><code>&lt;a href="javascript:sendEmail('5237952A6F67618E407373772E6063212E6175')"&gt;Email Jonny&lt;/a&gt;
  </code></pre>
  
  <p>I already have the javascript methods for encoding/decoding a text value from the meaningless string above, but am not too sure as to how to approach this with SharePoint in mind.  I'm thinking a custom control and/or custom J-Query?</p>
  
  <p>Any help would be much appreciated!</p>
  
  <p>Jonny</p>
