Hey Jim,
Hope you’re keeping well.
If I recall, you don’t have to register your models anymore. Just yourself, and pay the 30€ fees.
You will need to put your IAA number on all your gliders.
The training is the IAA one that you need of course, but to be honest, can’t remember how to access it.
I get to my laptop and check. I did my renewal last year, and if I remember, it was a simple process.
Also, have you check what that says in the MACI app?
