This is Open Source software, this is not a license which allows to steal ideas and use them in your own code. Give credit where credit is due and make sure you understand the license before you claim the code as your own!

Notes:
I would also suggest to disable the javascript which disabled the Submit button as it creates problems if the user has to go back and fix a mistake (with Firefox). 
	Change this:
 		<form id="register" method="post" action="register.php?action=register" onsubmit="this.register.disabled=true;if(process_form(this)){return true;}else{this.register.disabled=false;return false;}">
	To this:
		<form id="register" method="post" action="register.php?action=register">
