Need some extra help? During the semester, we'll produce a number of online tutorials -- Flash simulations, YouTube podcasts, etc. -- to give you help on content, tool usage, and the like. Have a topic or tool that is giving you a hard time? Let Mr. Gotwals know (you can use the "Contact" form at the bottom right), and we can quickly produce a podcast or simulation to help you out!
