Hi Sarbar! How are things? Putting it up for free as a sort of promotional thing is an option that Amazon offers with some limitations. I might do this at some point. What I've read is that it's recommended that a few reviews be out there for a book before doing this, which makes sense to me. No reviews are out as of last I looked --- and I'm not inclined to ask friends and relatives or others to prime the pump with overly glowing initial reviews, I hate that when I see it for other books or other products.

If/when I do that I'll try to remember to post something here.
