Thought I'd post an update, so if it crops up again there's some starting points.
Thanks for the PMs, people - much appreciated, you know who you are.
France - contact
ANPI which is the French Instructor Association. André Paris (email on the site) is the guy who appears to run the seminars. There is one in Rennes in mid September, but logistics make it a problem for me.
I had a PM about Aerofan FTO based in Madrid ( I think their English language web site is at
www.aerofanifto.com ) - again I couldn't get info about an earlier seminar than October.
So, I'll be at the OnTrack seminar in October - looking forward to that !
