Last command
From ThresholdRPG Wiki
With the last command, you can recall the last screen of messages from a channel, or says/tells sent to you. Obviously, this can be very helpful at times.
Usage
last <say/tell/channel>
Valid Channels
Special Note
Also, if you type just the channel name, it will function as if you typed last channelname for channels like threshold, trivia, sports, etc.
