Hey Filipe,
I think I met you in Kinokuniya book store a few years back. You were looking at Mastering the Rubber Guard and I was doing my weekly browse to see if there was anything new. I recommended the book and we started talking about Jiu Jitsu and your school (I think it might have been in Chippendale at the time?).
Anyhow, if said person was in fact you, hello again and werlcome.
