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. http://www.magentocommerce.com/magento-connect/email-not-required.html
Thanks for any help.
You could do something similar to what the extension does.
You could create a gmail (or if you use google app for you company email) or a catch all email
Email Format
Then remove the validation js from the email field that make it required in your .phtml.
Then create a custom module that override your checkout controller (assuming one page checkout)
/app/code/core/Mage/Checkout/controllers/OnepageController.php
(You could also do this using JS, where you pre generate the email address (in a hidden field or variable) and if email field is left blank you append/post it before submitting your billing form)
