Some times qhen I leave my computer on, I receive some messages, but if someone turns off the computer, those messages are lost...

I don't like to use the "conversation history" option, so, it is possible to make a script that records the received messages so if the computer is turned off retains the message till I request to show them, and that way I get an option to delete the "received messages"...???

Thanks in advance ^^...
