I changed the Moodle format for the 2 classes today, from a date based (1 month long,etc) to based on chapter or unit type thing. I did this for a couple of reasons. First is that these courses aren't meant to be completed in any certain timeframe - actually people can take them as fast or slow as they want. Since they are actively in production however, at the moment you can only take one as fast as I can finish it. But that won't be the case once the course is completed - at that point members will be able to access the archived classes, and begin taking them whenever, going at their own pace for finishing the material as well.

Also I think this format better suits the material itself - as all my programs are sort of chapter based rather than time based. It may take a couple of months to get them completed - but once done, each class will be online forever which is nice.
