For me WIZIQ and Flashmeeting sites are very useful. I had really good time using them.  For me  the Flash meeting is better compared to wiziq because only one person can talk at a time and is free of noise and have queue system for the next person to talk. Good part about is WIZIQ is its white board.

I added comment on the Seesmic video, the voice threads, the comic strip, and the survey.

Finally I will say that everyone should take the experience of this course. Information Technology tools for engineers.

Thank a lot Dr. Alam
