PLAMO: Re-WiredWolf - Plastic Modelling, Share & Learn

Any 1 knows what is this paper ?? I found it in my MG Wing Zero Custom but its all in japanese and there are numbers inside, some kind of lucky draw ??

It says to register with the gunpla number at that site.
But there doesn't seem to be any page in that site about this.

Maybe its over already?
Ok found it, its here:
http://bandai-hobby.net/goc/comingsoon/index_pc.html

They are currently preparing the service for use with the gunpla number.
But it will be only for within Japan.

icic, tot it was a lucky draw or some serial to exchange for something....

Thanks man !
