Hi all

Those implementing this becareful with this
ALTER TABLE `xcart_orders` ADD UNIQUE (
`email`
);

this will only allow a customer to make an order once from your site ...the next time they come they you will get a sql error..as it only allows the customers email address once..in the order table ..to reverse this use

ALTER TABLE `xcart_orders` DROP INDEX (
`email`
);
