My name is Marco and I've become a member here. Unfortunately for you - and myself! - I don't speak Japanese, but I hope that writing in English is good enough.
Regarding myself: I live in the Netherlands, I'll turn 30 this year, and I teach at a secondary school. I am also a member at the 110 Club, and I am an administrator for the GRG. As a GRG Administrator, I can actually tell you that we really appreciate what you are doing, as it helps us cover Japan much better!
I will post a message on the 110 Club to confirm that I have become a member here.
