easiest step in establishing a presence on
the web is to register your domain name (something like
"kmdesign.net"). For less than $10 per year (for most common
domain name types - including the ".com" suffix) you can register your
own name - in just a few minutes - at AlphaWebmasters.
no reason why you shouldn't handle the domain registration yourself.
Don't let a web designer try
to tell you that they should register it for you. If you ever have
to make changes to your site hosting or maintenance arrangements,
it'll be much easier if you have control of the domain name.
