Today we pushed a redesigned settings page that will make it easier to find and edit settings for your personal account as well as any organizations you own.
The major change is having easy access to settings for your organization. In the previous design you had to fax us your social security number, drivers license photo, and send us a hard copy of your Passport before you could find the link.
Now it's right there with the rest of your settings.
For GitHub Enterprise customers this will be in the next regular release of GitHub Enterprise.
