I see, that's kind of annoying.. It'd be better to randomize or even choose challenges ourselves then. But if he really doesn't wanna do it regularly, we could always give each other the next phase I guess xD. I fear the challenge wont last long if he doesn't keep posting new challenges for everyone.. Also, what happens if he's done with his run? Will he even continue? We shall see how it turns out :p.
Nice to see you again tho ^-^
