I would have to check but none of my WT(F) documents/certificates have anything to do with rank. They are for competitions/levels and tourney contributions.
Well that makes perfect sense. Because WT isn't an art. It's a sports governing body.
I think if the "honorary" BB were given to someone skilled who never officially studied the art, that would make sense.
If you say so, but to me... not so much. They don't know the art. I feel the same way about honorary doctorates and such. If it's not earned, it's silly. Just give them a Certificate of Appreciation or some such.
