Hi Jane,
After a few years using Moodle, I've come to the conclusion that it's better to outline entirely what you want to do - start to finish -- and then ask how to accomplish it, rather than try to accommodate the software. Moodle is all about trying to meet people's needs rather than people meeting Moodle's needs.
So, tell the forum what you want from start to finish, and folks should be able to tell you how to accomplish that.
Of course, you may get some clarifying questions Also, feel free to DM me if you don't know how to phrase something. There's real world speak and Moodle speak. I'm half good at the latter.
