/spec playername
There's also a whisper command, I think it's /msg
It's /w and last I checked it's only in a 3 block range. If it was changed, that's stupid because it messages all people within that range and 55 blocks is the normal chat range....
Anyways commands are:
/list (green is tributes, blue is spectator. At bottom it says player count, tribute amount and spectator amount)
/info (information about server you are on: The number, Loaded maps, current map, tributes, spectators, total players, time left)
/top (players with the top amount of points in the region you are in)
/records (Personal info that it says in your leaderboards but not all of it. You can also do /records (name) for a person that's on that server right now's stats.)
/w (message) (whispers everyone in a 3 block range... From what I know... Also, /whisper)
/spec (tribute name) (Instead of having to continuously click just do the command to spectate the person)
/suicide (kills yourself if you are a tribute)
/help (tells you that you are not allowed to do this command and some stuff about fairies being mad or something, it's useless so don't bother with it)
