i checked out the answering machine script and I was wondering if there was a simpler script that sends a specific reply to a specfic contact when they send a message.

for example:
I have 3 contacts online
Contact A
Contact B
Contact C

Im already chatting with Contact A
Contact B starts to chat with me, I send a message "Be with you in 5 mins".
Contact C starts to chat, so i send a different message "Go chat with Contact B".

is this possible? and/or is there a script that does this?
