I spent some time today and went through the wiki and updated quite a few of the promo codes. Some of the promo codes had expired more than 2 years ago. I did not update all of them. I feel like this could be a very useful thread, and the wiki is the best place to keep track of the codes, so if you try to use one of the codes in the wiki and it is expired, the please help everyone out, and remove it. Also posting the expiration date of the code in the wiki will help too.
