Just one comment - these forums (HWS and SEM for example) don't appear to have much curezone traffic; there are many other popular forums here. But that isn't necessarily a direct reflection of their efficacy. I don't know about SEM, but it sounds like HWS is a pretty busy business and there are many who are interested in using this method. But it hasn't had much traffic here at curezone.
