Hey everyone - unfortunately we had an important meeting scheduled right over this time today so we're going to have to cancel this. I don't know if we'll be able to reschedule but feel free to email me with questions (email in HN profile)!
Hey! You should definitely use Voxli (disclaimer: this is a shameless plug since I'm a cofounder). We're easy to use web based voice chat.
1) You get your own URL so you don't need to conference call people in each time.
2) We're client-server, so you can have tons of people in each conference room
3) We're free since we're in beta =)
When you join, you get a randomly generated name (we thought it would be more interesting than "Guest1234")
There are a couple of us in there now =)
Checkout http://www.gomtv.net/ if you are interested in "studying" independently, but don't know Corean =). They flew an English speaking guy to Corea to provide live commentary on their league matches. Recommended!
