Thanks. That site was really helpful, and I also found another good resource here: http://www.dwmbeancounter.com/moodle/
Thanks again, if you have another other ideas for good class discussions or projects please let me know. I have some projects to start (simulations and other ideas but need additional filler work - problem sets and additional practice exercises) that they can work on. I'm making most of it up right now but it's starting to get a little repetitive for them.
