To be honest, being a mod is probably the biggest reason I'm going back. I still feel responsible for Challenges, since I've been its ultimate overlord for more than 3 years now. I don't really post regularly anymore, save from few instances when I feel bad about not posting, so I go to few threads all over the forum and post there. At this point, I'm not sure if I would bother if I wouldn't be a mod.
But please don't take this personally. I think people here are awesome and I have fun talking with you, but I can still imagine that I would be okay if I just never show here again and didn't talk to anyone from here.
