I could be wrong about this, but I think the duplicate email field method is something developers started using to cut down on invalid registrations as a result of typos. It seems the theory is that by using two fields, the user has to enter it twice and validation code can be used to make sure they match, thereby decreasing the chances the entered address is incorrect. I'm not sure this would stop spam-bots, so I'm not sure that's a reason behind it, but again, I could be wrong. An alternate solution is to send the new user a confirmation email and have him/her click the link in the email to confirm it was received and the address is valid. But this is far from perfect. You'd probably have just as much success by asking new registrants to confirm the sign up information while offering the ability to edit it before saving it to the database. I've never tried this personally, but it's an idea. Any method will have its flaws. I'm so reassuring! -r- ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)! To post to this list .......
