Is Billings CM only? Would Billings work for someone who CCL NFP doesn't work for? I know Creighton is what most would recommend for me, but the instructor in my area (well, an hour away, but doable) was really rude on the phone, had no idea when the next intro class would be, and overall seemed like he was REALLY inconvenienced by me wanting to learn the method. I corresponded with him a few times over the span of maybe 2 weeks, and HE called ME (I had emailed), so I know it's not just that I caught him on the phone at a bad time. This was 6 months ago, so I might just try to contact him again and see if he's still a jerk, but i was thinking I'd look into another method.
Also, can you give me a basic idea of the class structure for Billings? Like, for CCL NFP, you attend 3 classes that are a couple hours long each. What is it like with Billings?
