1) Unfortunately, I couldn't turn in. Away from reliable internet connection.
2) The fact that it HAPPENED!
3) Quite a few, to be honest...
a. Show the specific donation levels on your website, and show which user got you to that level.
b. ONE PLAYER AT A TIME!!! It's kinda cheating to have 4 guys all going at the same time, shortens the time significantly. Everybody else can really just comment on what's going on in the game, or just spend their time shooting the air. If it looks like you guys are having fun, then your audience will also have fun.
c. Tune in to the Mario Marathon starting June 24th and Desert Bus for Hope this winter for more ideas. Those guys do things correctly, they have a massive audience, and gave $82k and $209k (@_@) last year, and will probably give more this year.
4) Yes, absolutely.
5) Sure, why the heck not?
6) Advertising, advertising, ADVERTISING!!! Get the entire Pokemon community in on this. Plan ahead. Go just short of spamming the video game community for exposure. You'll be amazed at how big your audience can become if you advertise in the correct places.
