Hi, I noticed in Essentials they have the /sudo command. Which makes another player perform a command as if they typed it in the chat box themselves, I wonder if someone could make this as a separate plugin as I don't use essentials, I have tried searching for it on the forums and no luck. Thanks!
http://dev.bukkit.org/server-mods/admin-chat/ there have the /fsay It is a "Force Say" command, which means typing /fsay Notch Hello! will make the player notch say "Hello!" in chat, if he is online. This also works with commands "/fsay richardred15 /suicide" will make richardred15 suicide. Console can use fsay
