Have a separate form to REGISTER and one separate for SIGN IN to be able to have different URL's for membership payment enrollments and sellers can't register unless they have paid the enrollment fee.

I need to charge membership enrollment for new users and the way the SIGN IN and REGISTER on same page allows new sellers registre without paying fees. Also if we don't get notifications of new sellers we would have to manually ask them to enroll and communicate this to them which it may turn them off and not sign in.

Is better to have clear enrollment options from the beginning and separating the REGISTER and SIGN IN forms will facilite this.

Is really simple to duplicate this page and hide the CTA with HTML, so it should not take too long to offer this feature in our marketplace.
