REPLY .
Usage: reply <message> or . <message>
This command will send a reply to the last person to send you a message using TELL. It works just as if you had typed 'tell <player> <message>' but makes it a bit easier. It can also be very useful in case someone invisible sends you a message.
Example:
Ras tells you, 'Hi!'
reply hey You tell Ras, 'hey'
Someone tells you, 'I am your secret admirer.'
. Who are you? You tell someone, 'Who are you?'
