the only thing I'm worrying about is the speed. Two threads might proceed in different speeds. But other than that, I think i can handle it. I can find another RPer to handle one of the twins, and I'll handle the other. Maybe you can help too :)
Twin Roleplaying is a new generation to Roleplaying :D
the transition, now we'll have to wait until two sides are done, and have passed a certain 'checkpoint' in the story, then I can announce and start a brand new thread with the third, final name. The plot would probably be 'build a device that can send you to another world' , which sends you to the alternate world.
