Is there a mod that makes registration quicker?

[cheat-master30]

Or more specifically, reduces the registration to the fields on the actual form, a tick box for saying that the member agrees to the rules, and a form for date of birth that gets checked when submit is pressed? Seriously, I'm thinking that the three page registration thing used in vBulletin by default is ridiculously long winded and is probably putting off quite a few new members.
