cant be done until tournaments are automated. ive explained this already in another post of mine but there is no such thing as a "tournament" described in the game server's code. the tournaments we play in are INGAME (keyword) organised events and not objectified in the game server itself.
however, GMs that host the tournaments could be given a command to display official event winners but thats just poor game design, especially when we know how late the staff can be with just the prizes.
guess we just have to wait till the developers decide to add in automated tournaments
