After using "Wimba"

I used "Wimba" for the presentation of my project in one of my classes last week. It was my first experience to use the tool.
Wimba is a tool for on-line classroom. We prepared headsets, and then we could talk and listen to each other on the Wimba website. Because it has a simple navigation, I could use easily though it was my first.
There were some impressive functions. I could raise my hand by checking the button shaped a hand. Also, the instructor showed some web sites on my web browser. He controled the browser on my computer! I didn't need to copy and paste the URL on my browser. It was amazing!
The sound was quite clear. We could chat while talking and listening to others. If you have pc cameras, you can see others. It would be more effective class.
