I think colours matter. If no black belt teaching, you have to
find an external coach. This is what our Aikido people are doing.
Nobody skilled in Aikido, so external coach. Unless your black belt
friends want to join RP and set up the club, if not, blue belt
doesn't seem to be a good reason for you to set it up.
But they good ma? Later I join liao go
home cry
You mean the basketball?
