So you have a MobileMe (aka DotMac) account and you’re using iWeb to build your website. But you want a catchy URL to give people, not that incredibly long and complex URL associated with your account. What to do?
First, you need to register your domain name. Lots of people use GoDaddy.com. I don’t. I use PairNic, associated with Pair.com.
(1) Log in to your Me.com account.
(2) Click the “person” icon (upper right on menu bar).
(3) Select “Personal Domain” (the last option in the left menu). You’ll need to associate your new URL with your account. Complete the form. Then Apple says you change the CName in your custom DNS settings to web.me.com. Click “done” and you’re almost done!
(4) Now you must log in to your account where you are hosting your domain name. Find the “custom DNS” settings (sometimes called MX settings – the interface will vary by host) and change the CName.
Some registrars allow you to choose how soon to publish the new settings. Others don’t. Sometime between 6 and 48 hours, your new URL should point to your iWeb-created web site on MobileMe. (That is a mouthful!)
