A few more folks have commented (unanimously positively) on the idea of creating a video-based course on how to create macros. I really am humbled and enthused by the positive feedback, and I appreciate it. Again, you can see all the feedback at my blog, located here.
I'm getting close to announcing something about the course. I'm leaning toward doing a "limited enrollment" course, at least the first time around, so that I can work more directly with those in the course to make it as good as possible.
Anyway, I may be ready to announce something about this in as little as a week. You'll want to keep your eyes peeled, as the the announcement will be in this very space.
Thanks, again, for the feedback.
