Immediate payment upon signup

I would like to have a new sign up be redirected to the payment form. I assume the easiest way is allow the person to fill out the sign up form, have them login, and redirect them to the upgrade membership page if their membership level is set to standard.

For the life of me, I cannot find anywhere in the code where I can add,

if(membershiplever == 'Standard') { redirect me to the upgrade membership page. }

Has anyone else found this solution or a similar solution which would still accomplish what I want.

Thank

I know it has been awhile since this was posted, but I figured I would tell what I ended up doing:

I edited dolphinroot/join.php, line:

echo _t( '_Join complete' );
echo '<br />';
echo _t( $sStatusText );

I change the top text to say "<b>Just one more step</b>"

Keep the <br/> in the second, and add some text with a link to dolphinroot/membership.php (I put a note that they will have to login first, but if you click the link, it will tell you to log in before you access the page, once logged in, it will take you to the membership page to upgrade your membership to paying)

Then I took out the         echo _t( $sStatusText ); line.

There is probably a better way to do this, but this is working for me. Makes it a lot easier than people not realizing they have to go to My Account, My Membership manually to upgrade to pay.

I do like the idea of a if standard member go to membership page on login, but that is beyond me.
