Does anybody use EasyOChem (http://www.easyochem.com/moodle/)? I stumbled onto it as I was looking for a way to let students draw structures in Moodle. It seems to provide that capability, but it looks like it all happens on THEIR servers instead of allowing instructors to use their institutional Moodle servers. I am a little nervous about the system because it seems to have amazing capabilities without costing a dime. I figure they need a way to make money, and I am concerned about how that works. If you have used this system, please share your experiences with us.
