http://starmen.net/Starmen is currently launching a campaign to in short, make sure Nintendo knows we want Earthbound and we want it NOW. They're going through the one route any Nintendo fan has known to really be a spot to voice your concerns, ask questions, and really get listened to by Nintendo, the customer service line.
Pitch in and help out. Don't spam, but give them a call and tell them you'd like to see Earthbound on the VC or Mother 3 in the US! This campaign is a 55 hour event which started yesterday, so there are intentions only to do this for a short time and mostly over the weekend, so let's get moving!

Option -0-
BE POLITE IF YOU CALL AND MAKE SURE TO ASK FOR BOTH GAMES.
Important: Don't mention Starmen.net or the marathon. (And I just heard they are now aware of the movement and are taking down a list of names of everyone who calls. That's right NINTENDO is recording the petition now and is actually listening. Make sure they know you're a new caller, give them your name, be creative about your request, something to let them know you're new!)
