I'd like to mention a new free tool that allows teachers and trainers to create on-line and printed assessments. It was developed after a 5-year work by me and 3 other colleagues. It's compatible with Windows, Mac, Linux and tablets, and it's very easy to use. A few thousands teachers are already enjoying it.
You can find it and sign-up free of charge at http://www.questbase.com You can also download a quick tutorial from http://download.questbase.com/support/en-US/tutorial.pdf
If you have any comments, suggestions, etc. I'd be glad to hear them! :-)
