Select the link for the online classes and follow the instructions. You can skip step 2 (paying for the class in the online store). However, I've changed key to lock out everyone else except for the folks here. When prompted for the Enrollment Key, use AHN-GPO.
I have the course in the store and available for sale now, so I would value any thoughts you might have in case I need to do some last minute tweaking.
I had a hard time accessing the course. I tried logging in with the enrollment key but that didn't seem to work. Probably doing something backwards. Perhaps others have had difficulties also. Seems like a nifty site.
Before when I tried it i couldn't figure out how to start it, but now I'm in and navigating easily using the browser back button.
It looks good, I just read the intro and first part "character" topic discussion, and i'm impressed with the wording of the intro, because it puts to rest any unintended perception by it's focus on interaction from a mutual and ethical perspective, and points to the benifits of that approach.
