As far as the donations go, I could be wrong but I do not remember seeing advertisements over there, like we have here. Plus I could be wrong, but I think this site is an advertising medium for remek's book. It was actually remek's interview for his book on the podcast "sex with emily" that brought me back to pe, and led me to the "gym".
BTW, I was not knocking the ads here, I dont mind ads on the net in general as long as they are not trying to fool you into thinking they are site content.
