So the idea is to see who can sing a note the longest?
My superpower is absolutely NOT wind control, nor is it sonic attack.
No, the idea is to see which of the team captains above can get the most cumulative time from people singing a note continually. So if, for example, Felicia Day has 11 people who each hold a note for 30 seconds and Rhett and Link have only five people who can hold a note for 60 seconds, Felicia would win.
As for "Why?", it's fun, and it helps us drum up some publicity. If, for example, Felicia Day wins because we all support her team, then there's a decent chance that she might notice and say, "Hey, who are all of these SaveCoH people that are showing up? And yay, they helped me win!" But really, it's something simple and fun that we as a community can do together.
