337997 Modify/merge site login

I have a script that requires registration and login by the member. IF the member wants to be an affiliate, then have to register seperate for an affiliate account. I want it modified to where when someone registers on the site, they automatically are registered as a member and an affiliate. They would have the same affiliate ID# and the same member ID#. AS it is now, it uses the same database already. I need this ASAP, so please only bid if you can start on this now and do this quickly. Thanks!
