I'm guessing this post isn't targetting me, but in case I understand this and submit something can you confirm what I need to do?
I just make a picture with some sore of bitcoin related announcement and e-mail that picture to the e_mail address above?
And I can win bitcoins? I will totally do that, but please correct me if I'm confused about something...
Yep just like that. But note this is non-commercial, i.e. make and ad for Bitcoin itself or something that is in Bitcoin community interests. For example, "do not mine in pools that have more than 50% of all mining power" as opposed to "come mine in my pool".
