Can someone please tell me why
www.radiomuseum.org is O.K. as a link from, e.g., this post or via a google search, but when I included
www.radiomuseum.org in a PM to a fellow member earlier this morning, and checked by clicking on the link, a '404 Not Found' appeared. I double checked that I had entered the link correctly, and couldn't see any errors such as mistyping, spelling mistakes, etc. so am puzzled. The forum member in question lives in Taipei (Taiwan) but I don't see why that should make any difference. Just checked and neither link works from this post, but
exactly the same URL works if entered in the Google Search Box.
