Login Script Beta Complete

It’s taken  a while, but I’ve finally completed a decent login script!
http://munkydesigns.co.uk/Scripts/Login/Index.php 
If you want to have a look, but not register, you can use:
u: username
p: password
It doesn’t look particularly appealing at the moment, but it all works (bar a few bugs probably.)
Current features are:

Fully object orientated system
Sematically correct markup
Server side and client side error checking
AJAX check username function

Hopefully over the next few days I’ll tweak it, refine the code, and get it up […]
