I'm amused by Jim's rant, which reads in part:

"... the address pointing to their site is something like http://www.someurl.org and they want the www removed because it is "wrong" and they have gotten a customer complaint!"

In case you are wondering, this is a DNS (domain name server) problem. I learned this while maintaining DNS entries in France a few years back.

DNS entries are configured on a DNS server -- usually close to the web server -- which trickles updates up the DNS hierarchy to one of the main DNS servers on the Internet and then back down again. This happens continuously until all of the world's DNS servers knows the right mapping of http://www.someurl.org to some IP address. Otherwise, no one can find your server because we depend on these DNS servers to translate addresses. The propagation usually takes a day or so.

Convention dictates that the administrator usually makes the mapping for http://www.someurl.org to the web server as well as http://someurl.org. Some DNS maintainers forget the entry without "www" and as a result it doesn't translate for people. Smart browsers realise this and get around the problem. If you put in http://someurl.org and the browser gets no response, it will also check http://www.someurl.org automatically for you.
