I have attended some of your presentation workshops and thoroughly enjoyed learning more about effective use of technology in the classroom. Do you use camstudio or something with similar capabilities. I used to use it but somehow it has been removed from my computer possibly by our school administrator. I have tried to download the free software again but get warning messages. Do you know if there is a genuine problem with downloading the camstudio freeware or are there some unscruplulous companies putting bogus warnings out to stop people using camstudio?
