When attacking another player, you must type the first three letter of their name, I am geussing it was made this way so if ur fighting with a friend whose name starts with the same letter as a mob, you wouldn't kill him. However, turn works with one letter. Not a big deal, but someone could accidentally pk a friend. Don't ask me why a follower of Enoch would be grouped with an undead player, if I find out about it I will punish them!

I think this was originally coded to keep people from going into secret exits without searching - you have secret exit HIDDEN DOOR and the only exit is OUT, you can spam:

go a
go b
go c
go d
go e

etc until you find the secret exit by typing "go h". I'm not sure about the code, but I'm assuming the function that finds the thing you typed in (ie, you type "look g" and it gets you a pointer to a goat) might have affected players, too, and not just exits.

My guess is that the turn command uses a different find function :P I'll put it on the list of things to do!
