I don't see why you'd want to use loadvars in this scenario.

public function onretrieveMessages(playerAccount)
  {
  temp.allAccounts = getstringkeys("this.msg_");
  for (temp.currentAccount: temp.allAccounts)
    if (temp.currentAccount == temp.playerAccount)
      temp.messageList = this.(@"msg_"@ temp.playerAccount);
  return(temp.messageList);
  } 
  //You'd call this part of the code, eg "temp.myMessages = this.retrieveMessages(player.account);"

The flags:

msg_Chandler="Hiya, how're you?", "Today I have a message"
msg_David="I am St...Dave", "hi Chandler! ;)"
