[Callers] Classes for callers?

Long time dancer, first time caller. Anyone know of any courses / workshops to improve my calling (in person or online)? I'm willing to travel for the right course. (E.g. Meet Me in St Louis had a calling workshop in 2024, but the schedule isn't out yet for 2025.) My wife and I were long-time Boston-area contra dancers who are now trying to bring the tradition to our adopted city in Austria. Almost all the dancers are new, I'm a new caller, and I believe it would help me to attend a class to learn more and get feedback on my technique. Thanks, Brian ---- Bringing contra dance to Graz, Austria https://contradance.at/
