store information without create a new account

[Manuel Coral Alamo <mcoral@dragonfans.com>]

Hello guy,
I have one  question for you , I want to create a new
account automatically avery time one user access to buy something, this
is important for me, because I need to store all the information the
user entry to te checkout.html form without the necesity to log in or
create a new account, this will be done automatically?.. I try with the
userdb function

 [userdb function=new_account
                   username="[value mv_order_number]"
                   password="[value zip]"
                   verify="[value zip]"
		   address="[value address]"
		   .
		   .
                   database="orders"

                   ]


but this only let me store the login and password, and no another
information that I need, as address, zip, etc.. please, let me know if
you have saw this stuff before.

Thanks in advance

Manuel Coral
