For the christmas promotion does the vouchers mean like 1 or 2 unlimited iron/gold membership or does it mean 1 month of iron/gold.
It means you can give either 1 gold supporter rank to a friend, or 2 iron supporter ranks to 2 friends each last a month
He means the vouchers that you can buy for 10$. If you choose to buy a supporter voucher for 10$, you can use it at any time and it will give the person who uses it a free month of diamond supportership
^This It is worth noting that you can only get one voucher, when I did it I had to instantly give the other supporter to another
