I think the generally accept convention now is that 
www.domain.org and domain.org both point to the website for 
that particular domain name.

That's the beauty of having a domain name that allows one to 
create sub-domains. Not all domain name seller's provide 
that option of creating your own sub-domains. My 
karsites.net domain is registered and hosted by my ISP, but 
I recently moved the DNS entries for that domain name 
(karsites.net) to my cloud hosting provider.

I can now administer all my sub-domain entries directly on 
the cloud, even though I did not register the domain name 
there.

Being able to create many more sub-domains on a 
single domain obviously means you only pay for the initial 
domain name registration, and you can then create as many 
other subdomains as you need. Take sourceforge.net for 
example. Each project has it's own sub-domain under 
project-home.sf.net

Anyway, I'm bantering on, and going a bit OT now!

Kind Regards,

Keith
