when you signed up for a bravenet account that was all you got
NO FREE DOMAIN
But you can have a Free site/subdomain if you want it
just click on the websites tab and a pop up window pops up and you chose the use a subdomain
then another window comes up and in that box area you put the name you want. Make it easy and simple and no spaces in it's name and then you will have a
xxxx.bravehost.com site
you will then get 10 days without the bravenet banners/ads at top and bottom of your site so you will have to make your site to work around that.
then after that time you will see the ads. Now if you want to purchase premium hosting and buy a domain that is up to you as well
