Just a note, the major force of his fandom is now dedicated to getting him appointed as replacement senator for South Carolina. While he probably won't be appointed, that is where the focus is now in Colbert Nation. Not sure if anything Save CoH related will really make waves with the general populace right now, so it may be best to wait a bit until the Senate furor dies down.
It is a sad truth that, yes, Jim DeLint stepping down is captivating his Twitter Feed and added to that, North Korea announced they discovered Unicorns. So another Korean/Twitter-ish thing may not fit. Then again, they may make an association I don't see and find something funny.
We can only do our best to get noticed, and more pinging them means more chance of being noticed. If it doesn't happen before they shut down production for the year then we just get ready to try and be the first thing he notices next year.
There are also other media targets out there. GU Comics, PvP Online, Penny Arcade, Nodwick. All of those are Online Comics that use the Gaming Community as a focus. Nodwick's characters appeared in the CoH Comics as a back up feature. PvP Online's cast played CoH regularly and one of his characters, The LolBat, came out of a CoH arc in his comic. Join their forums, see if we can dig up some chatter. This doesn't end until we call it quits.
GU Comics
http://www.gucomics.com/comic/Focused mostly on Gamer Industry and Community humor. Has done several bits on CoH
PVP Online
http://www.pvponline.com/A Comic about an office that works on a Gamer Magazine. Lots of personal storylines, but they are all Gamers and had several arcs about CoH.
Penny Arcade
http://www.penny-arcade.com/More NSFW than the others. If cursing bothers you, probably won't like them. But they are another Gamer focused comic with a large fan base and active forums. Also responsible for starting Child's Play, one of the largest Gamer Charity Fund Raisers.
Nodwick
http://www.nodwick.com/Began as a pretty much D&D comic, and a long running one in Dragon Magazine. He did several comics about CoH. No forums, but you can email from a link on his main page and see if we can get his support.
