If you are a site subscriber, you can run your moblog, or any groups you set up, from a custom URL. To do this, you will need to do two things:
Firstly, you will need to use your domain management tool (provided by who-ever you bought your domain from) to point your domain or subdomain to our server. The IP address of our server is 22.214.171.124
Once that's done, simply log in to your moblog and navigate to the 'Domains' tab in your profile editor. In there you can enter as many domains or subdomains as you like to resolve to your moblog. options are available to have custom domains for both desktop and mobile versions of your moblog.
