Domain Name registration is not expensive at all - For $15 a year (compared to $35 charged by some) you can have your own whatever_you_want.com (.org or .net also available) - Or you can handle it yourself right here with this link for Domain Name Registration at Register.com

Now you need a place to put it. You have several options,... there are some places you can put your web site (and Domain Name) that are free, but, they most often require you to place advertisement banners on your pages. That's how they can do it for "free", they sell ad space on your site. Or we can host it for you.

What all you need on your site sometimes dictates where your site can be put. Some features require cgi programming and some servers are not set up for cgi. We have Unix servers with 250 MB space and many features including fully customizable cgi access and a full feature control panel using CPanel software. $10/ month for quality web hosting with a 99.99% uptime is a very reasonable cost. More space is available for those who need it.
