I was surprised not to find a thread on Stanley Publishing here already, so I started one, in case there are Stanley authors out there who want to publicly report their experiences.
As of now, Stanley appears to be defunct. Its website has been suspended, and there are author reports of non-payment as of the second quarter of 2012. Reportedly also, the publisher hasn't been responding to emails or other attempts at contact since July.
Stanley's Facebook page is still active.
