Whether it's because your nonprofit's name changed or you just want to simplify your CommitChange URL, customizing the URL string leading to your CommitChange account is easy to do from your Account Settings.
Just go to your account settings through the icon that looks like a gear in the left-hand CommitChange menu.
Click on Organization Profile in the Settings menu, and scroll down to the URL Slug section of the page.
When customizing your slug, you cannot delete the location information from the URL. Also, do not use punctuation or special characters except for hyphens. When you're finished making your changes, scroll down and press the Save Changes button.
