I was meaning to make a tutorial in order to help colleagues to see how edmodo works and I tried utipu but unfortunately I couldn´t manage to see the video I had recorded. The feature from utipu which interested me is the possibility to easily send the video to youtube. ADVANTAGE: can send tutorial to youtube. DISADVANTAGE: have to download program to your computer and :( couldn´t see the video I recorded.
Then, I decided to try screencast-o-matic to make the tutorial.
