title: Make email address not required in magento
body: <p>I'd like to make email address optional during magento registration.  I'm going to be adding an additional username attribute that users will be able to log in with (I've already got that part working).  What are the steps to do this, or is it even possible?  I found an old extension that does what I want I think, but it is out dated.  <a href="http://www.magentocommerce.com/magento-connect/email-not-required.html" rel="nofollow">http://www.magentocommerce.com/magento-connect/email-not-required.html</a></p>
  
  <p>Thanks for any help.</p>
