Well, someone needs to start this. So I guess I will, this time around.
Everyone who has made 100+ comments on songs in 50/90 is eligible to be in the Century Club. Other than the mods, we have no way of checking if it's so, but we operate on the honour system.
I would like to note that EVERYONE who is listed here, from the 100 level up, are part of what makes 50/90 such a great experience. You are the ones who listen and comment and give helpful feedback. So THANK YOU from the bottom of my heart to all of you!
