Hey, Free, way ahead of you.

I have already created such a channel, and outlines for several tutorial episodes. I have one recorded already, and I was about to record two in the past weeks, but a combination of exams and severe coughing kept me from being able to talk any longer than a minute or so. I do plan to record episodes and probably go live within two weeks, though. Gettin' better thanks to massive amounts of tea.

What I already have is a plan for a 50-something episode long tutorial series (as of now, further episodes will probably be added to the upcoming list) that'll include practically everything related to WA, not-yet-written contents for most of them, as well as another, non-regular series under planning. Plus a Youtube channel already set up.
I'd be interested in working together with another group, even if it's on a different channel in order not to cross each others' plans. It seems that your channel is aimed at a group of more experienced players, is it not? People who already know their WA well enough, and who are interested in classy videos of gameplay and other things. My target audience is the newbies, so they can get a pretty good view of how WA and its community works, while also trying to show new things to players who have been playing for a while.
