Its one of my faults...I specifically, when copying some sites do not give credit...Its a long long story....but this information which Canada has on its site, was actually copied itself from a website that existed at Humboldt State when a very good friend and geology teacher also ran the site...It was through her and Humboldt that my PPTOT came.....but anyhoo.....Most of the time I'll just paste a URL instead......at other times...I know things that others do not... This particular person at Humboldt, who is know the chair at another university was VERY angry at Canada for ripping off her information and making it look like theirs....She gave me specific permission to use that information in return for answering forwarded calls from Humboldt, which dealt with prediction---a subject which frequently came up but they did not know how to address.
