We're not connected with the people behind Minecraft, we're totally separate entities. The forums and wiki are community ran and while we've had brief discussions with the Minecraft company (Mojang) nothing has come of it. The general consensus is that we're best operating as separate entities, it means Mojang can focus on game development and we can focus on growing the community, it means that we can remain impartial (although whether or not that is an issue, I have no idea). We've never had a penny of Minecraft proceeds :-)
I'll send an email now, it'd be great to talk to some people over at cpmstar!
Anyway I'd suggest you guys chat with CPMStar - http://www.cpmstar.com, they're the king of gaming-ad-stuff.
Drop me an email (check my profile) and I'll pass you the addresses I know there.
