Olson, that gets added automatically. There's a scr-ipt that runs in the background that inserts links based on keywords. It is a way for the site operators to generate some additional revenue. I think most of us ignore it.
Thanks. Now I have one more reason to be thankful that the Ericson owners' site is privately owned and chooses not to accept advertising.
BTW, I am not talking about the conversion of gear-name words to links to stuff-for-sale on this site -- those words remain and just look a bit funny with their little underlines.
Adding text that the author never said, OTOH, is just wrong.
