Hey everyone,
If you are receiving email updates every time there is a new post for this thread, you can modify your "subscription" settings by going to "User CP" -> "List Subscriptions" or
click on this link.
You can change your subscription to "no email", "daily," or, "weekly" update.
By default, you are subscribed to any topic where you reply. This is useful for most areas of the forum, but for the giveaway threads, you probably don't want to receive an update every time someone posts a new reply.
(Note we're using words "thread" and "topic" interchangeably.)
