From time to time, people have a Voucher that is no use to them for one reason or another and promote them here to give away.
Basically, you will have to watch for the Threads when they appear.
As for this 10 digit Code, nobody that has written in the Thread read the Title correctly, you did and now you have shared that information out to the public, which you should have really done in the first place. I don't want to have a go at you for not making it public, but this is a public Forum for players like you, me and everyone else, so that information does help so many people out.
It's a nice fuzzy warm feeling when you can help people out, so, if you see other Threads that you know the answers to, try not to keep the information to yourself. Spread the good word.
MERRY CHRISTMAS
