Bethers:
Thank you very much for your answers, but as you are no doubt aware, the answer to a question merely generates more questions. Has something to do with the quest for knowledge or some such drivel!
First, how do I know wheter I signed up for a free domain name or not? I just clicked on the appropriate looking option and paid my money.
You are entitled to a free domain name - just raise a support ticket and Vodahost will explain what to do.
Second, if one has multiple domains, which I do, how does one handle them when trying to build a site? I currently have 2 top level domains, and I need a third one.
You can set up different folders in BV to keep the pages of each site separate. Each new site has its own folder within your public_html folder on your account. When you load a page to one of your add on domains, you upload it to your folder public_html/newdomain
If I don't qualify as eligible for a free domain as a new customer, is there a way to purchase one through Vodahost? I'm pretty sure there is, I just haven't looked for it yet.
Yes, you can buy domains via Vodahost - the url is www.vodahostdomains.com
Finally, what about this "Treasure Chest" thing? Is it something I should be interested in?
Treasure Chest is freebies and goodies for Vodahost customers - for example you can buy domain names for $2.95 here. You need to have a login, and to get one you raise a support ticket.
Thanks again,
Wayne
