John, we have been moving through the course at a pretty glacial pace in our study group....but we are still moving! :) This course has been tremendous. I fully realized this just the other day glancing again through a book I had picked up in the library a few months back. Just months ago it was completely incomprehensible to me, yet now I found myself nodding, recognizing, and even understanding the basics of things like symmetric monoidal categories. This was incredibly motivating, and furthered my resolve to keep working through the rest of the material.

I realize it's difficult sometimes to see the effect of all this incredible work you have put into writing and answering questions.....but it is there, and will continue to help those like myself for quite a while to come as I continue through the course.
