I may be changing it so that I am available to post twice a week, but either way yes, in a week I will skip if people haven't posted. As to the length of the lessons, it will depend on the class, you're in a couple. It will also depend on how the students comprehend the lesson, if they start to get it right away, then I can show a more advanced application and end the class. There is also going to be a mini-test, but I am trying to escalate the classes quickly.
