I want to create a simple user registration form with First / Last name, email, and password. We have used captcha and email verification in the past to ward off bots, but is there another way without using those techniques? I thought about encrypting the field ID names so that they aren't names username, password, etc. we tried openID, but 1% of our users had an ID they could use.

HTML :

<div id="openModal" class="modalDialog">
<div><a href="#close" title="Close" class="close" onclick="DisableAllPopUpTxt()">X</a>

And we have seen all these in a user registration form. But what if I want to add more fields to it. For example, take a look at this website, this registration page has a lot more fields for users to enter information: [URL] This regirtaion page has the information for Street Address, Suburb, Gender, DOB and lot more. How do I add these fields into my registration page. I have heard of something called profile. But how do I intergrate profile into this, if this is what we use to add more fields to user registraiton page. share a sample working code of user registrtion page with more fields.
