My goals were to learn to 1) Mount, 2) Taxi (up & downwind), 3) Fly - in that order. I only expected to get 1 & 2 in this session.
Wow, it really is like starting all over again. 'Impossible' went though my mind many times in that exhausting first session. Crash, crash, crash

After a long rest on shore I went out for another go. This time I started way upwind for some margin. My goal is to learn to mount, taxi, and control well enough on bother sides so that I can stay upwind. Maybe I'll try flying a bit too. This time both sides seemed to understand better. After a few initial fails, there was a 'click': something got clearer and I could feel the foil contributing. On a taxi, initially there was a lot of drag while the board was low in the water but I could use the foil to arc it upwind and as the foil contributed more & more it transitioned to very low drag quickly. Upwind was easy now. My dumb side started getting it too. Soon I found I was most relaxed on my dumb side and trying out S carves more than on my good side. It's nice to have two working sides now.
As I expanded my Taxi boundaries, getting better at control and speed over wider and wider ranges, and tried a few jibes (failing in every case), the feel of foil itself kept coming through. As I felt more at ease and able to anticipate accurately I relaxed more & more and enjoyed how razor accurate the foil acted. From time to time I couldn't resist and I'd un-weight the front foot to allow it to rise into flight. Oh Wow! Of course I fell EVERY time in some manner or another. My longest 'flight' was about 15 feet before wreckage, but it felt so SOLID under my feet (and so SLIPPERY - like a puck on a friction-less table). One time the foil shot up and entangled itself in my lines. That was scary and a mess to get out of.
BTW, the skim board mount is working really really well (in my tiny amount of experience). I was worried about it nosediving easily because it has very little rocker, but it's been very good. I think mounting it far back was a good move for balance. So far I prefer my back foot between the bolts, right on top of the mast. Once I start flying more I may change my mind. I am sooooooo glad I'm NOT using straps. I avoided many close encounters of the unwanted kind by not being strapped in. Keeping my feet in good contact on the board is not even close to a problem - so far.

For those of you who are considering foiling... I thought it may be worthwhile for me to share my plan, experiences, and learning curve. I'm looking forward to session 2.
