When I signed up for Kickstarter I did so to back a project on behalf of my son who didn't have a credit card. At the time the plan was for him to take on the account so we created a vanity URL in his name.
However, I have since taken over the account to I can back stuff on my own account and I'd like to change the vanity URL to something more "me".
I don't see an option to change - or even delete - this on the profile page.
Is there a way to change the URL or failing that remove it so I can create a new one?
