@igrep oh well, yes as you mention, it looks like a bit difficult for us to know the knowledge of audience, but I thought it was a way to deepen the understanding of all the audience. Of course there are also beginners. English lecture in front of the audience, especially
listening to Edward’s lectures is very exciting I bet.
I don’t want you to misunderstand. I NEVER push you. As fumi san said, how much developmental content we want, I agree with him.
Step by step I hope we could decide various things about this conference.
