I'm looking for an application I can use to teach my classmates how to program.
Well, I give some classmates courses of programming, and I would like a software that lets me share my screen, audio talk, chat, and send multimedia. I have tried Skype to accomplish this, but it gets really buggy or disconnects some of my classmates, and really don't like it for teaching. I have found oovoo, join.me, netsupportmanager, but NSM and join.me are paid or doesn't have all features I need. I'm using Mac and my classmates use Windows. Is there any software that I can use that meets my requirements?
