You weren’t online last time I was on, so I guess I’ll respond here ^_^
Anyone can be a judge, both parties just have to agree to use you (or bring in an additional judge if only one player chooses you).
Just offer your services whenever you see a dispute in all chat. Then others can volunteer to be enforcers, attorneys, ect.
Having an election would be fun, but I think we’d have to wait until the player base is bigger?
