1. I need to determine if another player is logged in before sending an AceComm-3.0 SendCommMessage() ( equivalent to a SendAddOnMessage() ). Otherwise, if I send a message to Fred and he's not logged in, I get the error message "No player named 'Fred' is currently playing." Is there something like a PlayerIsLoggedIn("Fred") function, or can someone advise me how to create one? Thanks!

  2. No there is nothing like that. It's easier to check if they're in your guild or on your friends lists.. but other than that you need to do a who request.
