Email account creation submission

Hi all,

I am using a simple account creation script suplpied by Ross to allow visitors to create an account and listings which will remain hidden until authorised by an admin user. The form works perfectly however I am also looking to have the form details and a welcome message emailed to the account creator (users email address is included in the form) with a copy of the email forwarded to ourselves to advise of a new account being created. Could someone please point me in the direction of any existing php code to provide this functionality which I can add to the existing script. Obviously there are many form to email scripts around the web but I am unsure as how to combine the email element with the existing account creation as the current scripts starts

<form method="post" action="">
<p>
<input type="hidden" name="submit" value="1" /> and there is no value in action could i put a value in the action quotes which would cause an email to be sent?

Thanks in advance.
