Is it possible for me to transfer shiai tokens between accounts at all? I won a gm tourney, on account of 'shovelling' skills, today and did it with my alt ( TeachR )

Now I have 3 shiais on there that I can't use with my 1 shiai on this account, so I was wondering if there was any way to get them transferred over here?

Also, if it is possible, who do I ask?

Nope, I don't think so. You could contact an GM, but I am 99% sure they won't do anything. I asked before myself.
