First, I would get a killer computer system. That would include a drive that isn't prone to conking out like hard drives are. It would be so huge that I would be able to back up whole forums and barely put a dent in the capacity of the drive. And it would have the most advanced and reliable Internet access I could get.
From there, I would get onto a good hosting system and host a massive apostate Web site. It would be like a master switchboard linking every other apostate site to mine. Of course I would have a forum that would, hopefully, get as big as this one is. Maybe more than one forum, since I realize there are different markets for different people (some tolerate foul language and flaming better than others, and there are people that prefer a Christian based forum). The goal would be to set up a massive educational work that would expose the Watchtower Society to everyone with Internet access.
And, I would get some software to translate the whole thing into Spanish (so Spanish language posts would get into the main system in English and could be translated into Spanish if the user wants it), Portuguese (for Brazil), French, Italian, Chinese (just in case), Nigerian, and any other languages that are in emergency conditions with potentially exploding populations of Witlesses. After that is established, other languages would be added so eventually every language where Puketower litter-ature exists would have access to the whole system in their native language.
