It would be nice if there was something like "/al hide" and then when a player has set an item with a codelock down it would reply with "An item was placed with your hidden code" I stream on our community servers and it sucks we cant use this because it shows the codes while streaming.

Just disable the in-game text confirmation until the dev replies? 

Added, wipe your config, data & language file for it to work (just some optimizations)

It could have been much more easier ;)

player.ChatMessage(string.Format(lang.GetMessage("CodeUpdated", this, player.UserIDString), player.net.connection.info.GetBool("global.streamermode") ? "****" : code));​

Didn't know that was possible, thanks!

n.p. :)

Keep in mind, you have to reconnect to the server after enabling streamer mode or the codes will still be visible in chat.
