Know someone to get on or know someone to talk back and forth with? I mean, you could use google groups interface which is awful but still sort of an on ramp to it (and free). Plenty of usenet services out there though. you could pay a buck or two to blocknews.net for a few gigs and now you have “premium” access. discussion groups will take a long time to eat up 5 gigs. the real problem is sorting through to find the active groups not to mention finding decent nntp newsreader software for your platform. actually someone just posted a few days back in alt.fan.usenet some decently active discussion groups. got to start somewhere i suppose.
