I think that this discussions gets back to issues about the transmission of skills and knowledge. I appreciate that George limited the number of participants when he hosted Ikeda Sensei earlier this year.....Of course I was too late to go but that's my fault.
This information is best transmitted in samll groups and the last few big seminars that I've been at have been too crowded to apply what the teacher was offering.
I really like the idea of some seminars for different audiences, everyone, shodan and nidan, sandan and up...
Just a few thoughts to add to a good discussion..
