Re: Postulates

Maybe this is it? Looks like there was some problem with the handling of the apostrophe in "Playfair's" in the url.

Re: Postulates

Try this:

http://en.wikipedia.org/wiki/Playfair%27s_axiom

The page is, I think, a recent addition.  Looks like they changed the page name slightly.

Re: Postulates

Hi bobbym,you're gonna have to give me more than that,all i know about internet is how to browse.

In the address bar of your browser you will see an url of the page. Copy that between the two url tags. For instance:
