Some very basic client side validation would be your friend. Just check for the existence of an @ symbol, at least.

  This. Another experiment worth conducting is displaying their email address as a checkbox near the submit button: (x) foobar@example.com is my email address where I can confirm my account [Create account button]

    Checking for @ (and some other basic stuff) would be ok. I don't want to confuse users with more checkboxes/displays than necessary. Interesting experiment? Yes probably, but I would need more data than I have now to get meaningful results.

  > Just check for the existence of an @ symbol, at least. "At least"? That's pretty much all the client-side validation you can do. The next step is sending an email to it. The specification of what kind of email address is valid or invalid is horrendously complex. I've seen too many sites reject perfectly valid email addresses. Don't do this. If it contains an @, try mailing to it. Let the user respond to that email somehow, and you've got the only reliable email validation and verification that's possible.
