Oh, excellent! I did hear something about this through the Kernewek grapevine, but hadn't looked at it yet. I'll have to give it a go.
I'm currently doing the new course of KDL (Kernewek Dre Lyther — Cornish by correspondence) in my own time, which I'd definitely recommend for people who would like to get a better grasp of written Kernewek, but the audio element of it isn't very strong, so it'll be good to have another course to do alongside it — and all the better to have Pol in it, of course. (I'm doing KDL in Kernewek Kemmyn rather than SWF, but there's not a huge amount of difference, mainly just slight changes in the spelling.)
