login to your bravenet account
click on the websites tab
then click build a new website
then click use a SUBDOMAIN
if you want the free subdomain
if you want to buy a DOMAIN and then get hosting those are 2 different entities
Too many people are clicking on the get a DOMAIn and that you have to pay for and more
so click the use a subdomain link and there is a box area where you type so your site would be xxxxx.bravehost.com and where the xxx part is put something simple that relates to your site perhaps
then click submit and then if that subdomain is ok it will bring you to your maintenance area for your site and you can start building your site using bravenet's editors if you want to that way or if you know html and want the freedom of designing your site truly the way you want then use that way
