Registration Form edits

Website: nighteyeslights.com
My users do not login. They do register using the hikashop form. Once filling in the form they move on in the purchase process, never to see the form again.

1)Is there a way to provide a link back to that form so they can edit it during their current session if they wanted? I'm using the business edition of hikashop.
2)How long does the store remember the user registation? I've had issues, when trying to register, saying this email address is already used. Where would that email be stored that it will not let me use it again to register?

Thanks

Hi,

1. Until he finish the checkout, the customer can go back to the address step to change his address.
2. The email is already in used probably because you used it before for a registration, if you use a never used email address on your website, you will be able to use it as many times as wanted.

thanks. i will check this out. much appreciated.
