How about a tutorial on youtube or this forum as something may come up fo many of us. So we could can ask questions during the week on a topic your discussing, and if there questions people are getting wrong or do not understand them, you could Answer. no?
We had considered those options, except the forum isn't instantaneous and its not as popular as Skype. As for YouTube, it's not particularly interactive, it'd just be me lecturing. The point of the tutes is that it's interactive

Btw guys, once you made your AN Skype accounts (if you already have a Skype account just make a new email address for ATARnotes to make your AN Skype account if you wish) add me - my Skype name is "ANthushan"
