Delete draft email message without having to confirm 'Don't Save'

Hi scripters!

This is my first attempt at writing an applescript. I have used other peoples scripts plus the example scripts as inspiration.

The purpose of the script is to update my Facebook Status with the name, artist and album of the song being currently played in Itunes. The status update is achieved by sending an email to the address that Facebook provides each user.

So I grab the info from iTunes and then create a mail message, before sending I display a dialogue box with the status update and a choice whether to send the mail or not.
When I choose not to send the message the draft mail window is shown with the dialogue box asking if I want to save the draft, cancel or not save.
If I have the new message invisible and choose not to send the mail it is automatically saved in the draft folder.

Is there any way of telling Mail not to save the draft when issuing the delete command?

Here is my script.


tell application "iTunes"
	if it is running then
		try
			set playerstate to (get player state)
		end try
		if playerstate = paused then
			set trackPaused to " (paused)"
		else
			set trackPaused to ""
		end if
		if playerstate = stopped then
			return "Stopped"
		end if
		
		set this_name to the name of current track
		if this_name is "" then set this_name to "Unknown"
		set this_album to the album of current track
		if this_album is "" then set this_album to "Unknown"
		set this_artist to the artist of current track
		if this_artist is "" then set this_artist to "Unknown"
		set cr to ASCII character 13
		
		
		set totalData to "♫ I am listening to '" & this_name & trackPaused & "' by '" & this_artist & "' from the album '" & this_album & "' ♫"
		
		
	else
		"No music at the moment"
		
	end if
	
	
	set theName to "Facebook"
	set theAddress to "XXXXXXXXXX@m.facebook.com"
	set theSubject to totalData
	set theSender to "YYYYYYYYY@gmail.com"
	tell application "Mail"
		set newMessage to make new outgoing message with properties {subject:theSubject}
		tell newMessage
			-- Default is false. Determines whether the compose window will
			-- show on the screen or whether it will happen in the background.
			set visible to true
			set sender to theSender
			make new to recipient at end of to recipients with properties {name:theName, address:theAddress}
			set send_q to display dialog "Would you like to update your Facebook status to your current iTunes song?" default answer totalData buttons {"No", "Send"} default button 1 with title "Update FB Status"
			if button returned of send_q is not equal to "Send" then
				delete newMessage
			end if
			activate
			send
		end tell
	end tell
	return totalData
end tell

Any suggestions on improving the script would be appreciated.
Like being able to define theAddress and theName in preferences so they are not hard coded, getting it to run in the background and pop up when the song changes (how annoying would that be!!?)

Thanks
