Can I use my own web address? Or do I need to use sitename.businesscatalyst.com?
You can do either. Most people prefer to use their own URL – i.e. www.yoursitename.com. You don't need to use the yourname.businesscatalyst.com address that is assigned to you when you first sign-up (although you can if you want). You have two choices - you can either let Business Catalyst host your DNS (you need to re-delegate your domain to us), or you can create an A-Record in your current DNS hosting service. Most businesses opt to use Business Catalyst's DNS, it's free. We've got an article that will help you out here and we make it easy for you – you tell us how you would like your web address to appear, we ask you for a few details and can then take care of this for you.
