It's not a separate network from the Internet. It is, as CottbusFiles says, a forum/mailing list/internet community, though I think "tightly regulated" is inaccurate. I would expect that it's more than a single site, probably a loose network of social networking pages, Yahoo and Google groups with mailing lists, with some people actively involved in national-scale communication and most sticking to the local scale except when one of the former group calls their attention to something. Since it's composed entirely of minor practitioners, they have little trouble using modern computing technology; by game rules, most of them would need to expend active effort (take mental stress) in order to hex a well-grounded desktop.
