If this is already possible, please tell me how to do it, and i've searched and found nothing like this...

Would it be possible to put a /exit or /quit command into the Plus! program so that when you type and enter this, it would automatically log you out and close the MSN Messenger program? Times this would have been really useful to me.

Edit: I know that this sounds familiar to the /signout feature, which i use a lot, but it's different to what i'm suggesting...
