Hey guys,
I'm the author who posted that story on GamerZines.com. I think the best thing you can do is send emails to websites like Eurogamer, VG247, Massively, Gamespot.com, GiantBomb and others letting them know about your cause. A lot of them have links for news tips, so just send them an email talking about group numbers, the petition, what you want to achieve and the sort of options you guys are exploring regarding making your voices known to NCsoft.
As a fan of City of Heroes, it was actually the first MMORPG that properly got its hooks into me, it would be great to see you guys get a response from NCsoft.
Cheers!
