So what do you need to do to make this work for your own pages? Principally, you need an Internet host computer where your files will be stored and sent back ("downloaded") to users world-wide upon their request. Most internet providers (like AOL) will provide their subscribers with a limited amount of storage to hold their own pages. Some internet providers (like MTN) sell space for webpages; if you need lots of space, this is the route to go. TCUUCC purchases enough space from MTN to host several UU congregations; each congregation (and Prairie Star District) has its own subdirectory of "/web-hotel/unitarian" (on MTN's computer) where it can store its own pages. The UUA also makes a limited amount of web space on its computer available for member congregations.
You do not need your own domain name, like "unitarian.org". Ordinarily, you will use the domain name of the organization providing you the space, like "aol.com" or "mtn.org" or "uua.org" (or "unitarian.org" in the case of congregations using space provided by TCUUCC.) If you want your own domain name, you must arrange that with your provider, and you must register the domain name. (Most providers can do this for you, but they will charge you the registration fee, which currently is $50 per year for a minimum of two years.) The advantage of a domain name is that you can make it recognizable, and you can take it with you if you change providers, so that your "web address" doesn't change.
