How do I change my username?

Once you have chosen your username, it cannot be changed. However, when you set up a Display Name and URL your username will always remain private. Your Display Name and URL are visible on Airgigs and both of these can be changed at any time. 

You can set a "Display Name" in your profile settings:

You can also change your profile url on the profile settings page. It's in the blue bar at the top.
