well, first of all i have to say that i didn't read the whole thread, which means i did only fly over it.
but to my mind the most important basics for a PC are:
1 - take only a few members, which means ~ 5-6, should form a PC (too many opinions...and so on)
2 - diffent countries, different life styles: the members of a PC should come from all over the world, e.g one from the USA, GB, Australia, South America, Germany/Austria, alright?
i'll throw in myself later.
