Something like that ^ .
(it made sense at the time, something along the lines of "squid levels, beep beep snoozing Pete, is it all balanced?" ) :Y

(Sorry, couldn't resist. Personally i have no issues with selling out the Guests with google ad words.)
I endorse this idea.
I also endorse Matts Google ads for Guests idea.
