Vanity Subdomains
Vanity subdomains are a great way to get up and running quickly. All users receive one vanity subdomain based on their username. Depending on your plan, you can add additional vanity subdomains to your account.
To add a vanity subdomain, go to your Dashboard > Account Dropdown > Domains. Select the + Add Domain button, and choose the Vanity tab. Enter your new subdomain, and you're off and running.
