Just a quick post to let you know that we have added an often requested new function. That is, the ability to delete existing access vouchers. This function was initially removed to stop people accidentally deleting access vouchers which had already been given to customers (and the ensuing problems that caused!) but we have since received numerous requests for this capability so it is back by popular demand, albeit in a slightly different format.
On your voucher administration page, click on the voucher you would like to delete to bring up the voucher's details. On the voucher's details page click the delete voucher link. This will delete the voucher from the system and it will no longer be visible to you or usable by customers.
Please just make sure that you don't delete vouchers which customers are still trying to use!
