Shane, sounds like you worked hard on it, shame it didn't work out for you.
Did you customise your template too out of interest?
I can understand why you were concerned to leave it for too long because of the earnings, but as Carey has said in this thread hopefully in time rankings do return (as has been the case with some Acorners I believe).
Indeed, I wasnt expecting to just install it and leave it. I customised it a bit on one of them (the one I've left live - slight layout changes, w3 fixes etc). I put it back live a week or so ago and will leave it for a few months.
As it happens, the site made a sale yesterday with a click from Yahoo - was a bit of reminder that people do use other search engines.
