A Google prompt suggested a custom URL for my Google+ account and YouTube account. My favorite “LPH” is too short so I compromised and went with LPH-TUX. The custom URL is google.com/+LPH-TUX and seems to role over to plus.google.com. The plus is rather annoying but it is better than all the extra letters in previous versions of Google+.
Did you get your custom URL?
