Does anyone know about the Power Station that Tribe is connected to? Facebook? How do they work? How are we allowed to use this service free? There must be a major computer somewhere that all is connected to perhaps? A power station? Someone has to pay the power bill somewhere right? How are we able to connect here, chat, post ads, post pics, scroll forums etc... for free???

I am very very curious.

Thanks.

A link would be helpful, that explains how the internet works.
