You're right, jens, it isn't there any more. The instructions were correct when I found the lat/long for my address some time ago, but it seems they changed their UI.

You can still get the data from mapblast, though. Fill in your address, and get the map, then zoom at least once so all the CGI parameters will get filled in. Then look for the CT parameter in the URL (it's a GET form, so it's easy to read). Mine reads &CT=40.0706471%3A-76.314855%3A20000, which makes my latutide 40.0706471 degrees N, by 76.314855 degrees W. longitude. However, this is decimal degrees, and we want dotted DMS. So, to convert, in each step I read off int() of the current value, then multiply the decimal part by 60. Thus, I'd put <!-- location:latitude=40.04.14,longitude=-76.18.53 -->. And thanks to you I just checked my homenode and noticed I didn't update it when I moved.

However, this, while easy, is hardly trivial. Another place to try, from a quick google search, is geocode.com's Eagle (US-centric)

One place I wouldn't try, BTW, is terraserver.com; not only are they MS, but they don't see to make any useful information without being a "pro user".
