Move Registration to new system

We are upgrading our social network. We currently have PHPIzabi installed as our main installation. It is PHP/TPL based. You can see one of our races here: [login to view URL] We have a Credit Card system installed on the old system & we want to port it over to the new system. As you see in the race page, people can click to register and it takes them to a registration page with credit card info attached. The new system is Social Engine - which is also PHP/TPL based (Smarty). So this should be as simple as copying the lines needed out of the old PHP/TPL site & plugging into the new site. We will want a normal registration process for users who do not register for races. then a different registration for those interested in the races. The race registration will either use the point system or the credit card system. So to wrap up, here are projects involved: Make registration possible with credit cards on new system Integrate point system with race registration Integrate "events" with races - we already have "events" plugin installed & operating.
