Hi all,
I did not realize my question would post so much debate. I have used blackboard collaborate as a student before and is good tool to do online teaching. So back to topic I gather that most people tend to use:
1. Blackboard Collaborate (Paid)
2. WizIQ (Paid)
3. bigblubutton. (Open Source)
Any other open source projects that teachers use besides these?
Regards
Terry
