Hi, and overdue thanks for the amazing ecosystem you're creating.
I've just created a wiki page with the following info:
"BIM Supporters provide free - you'll need to register for a free account - courses covering:
IFC - Learn about the open BIM data standard Industry Foundation Classes (IFC) MVD - Model View Definitions define a filter on top of Industry Foundation Classes
Most of the material is video, with some quizzes/tests at the end of modules. The material is concise yet suitably in-depth for beginners to the topic."

It's been helpful as I descend into the depths of all things IFC. Hopefully it's of help to others.
