Before this platform, we were organizing our virtual meetups (we've had over 50 study sessions already) through mailing lists and google calendar invites, so having a platform has been a vast improvement over the status quo so far. More info. about the history of the community here: http://hangouts.codebuddies.org/about
The project is free and open-sourced (and the platform is built on top of Telescope, a meteorJS app and still in beta), so feel free to file a bug if you see any problems!
