I've never seen anything over here that would make anyone feel they need to be exclusive, and I imagine the same would apply at AA. As more people are finding AP the pinball content is growing, and certainly the restoration side of things here is second to none - AND the admins gave Coconut Island a "home" right at the start, which made it very welcoming for nug and I (as well as filling a big void for us). I still spend time on AA as well, and RGP, and would probably join any other local forum specializing in pinball too.
