I saw on the new ideas.infusionsoft.com (Which is AWESOME!

THANKS BRAD) that a few people were wanting the web forms to verify email address, this can be done with a simple java script on your website, attached is the documentation for it, how to etc... Not only does it check for email, but you can use this to check for the required fields, this will give a user a pop up box with the error, instead of being redirected to infusionsoft required fields page. That way the person doesn't have press the back button to go back to your web site.
