You may use your own domain. All new accounts are initially set up with 512 MB of web space. After you have a working web site on line for 7 days, are using 50% or more of your initial allotment of space, and are abiding by the Terms of Service (TOC), you make a request on the forum for unmetered space. I would recommend that you read the TOC. A link to the TOC is found at the bottom of each page under the "Legal" heading.
