Okay, here is my input for now:
It says we must find the key as a group, so I'm guessing it is IMPOSSIBLE to do alone. I am not sure of it, that's just a guess.
My other guess is that when we sign up, the account gets our computers "fingerprint". In this way, it is able to give certain information to certain accounts (aka, what I see might not be what someone else sees).
Now that we're all in, let's DO THIS THING!!!!
