Ooohh, mysterious! Yes, you can make an anonymous contribution by following these steps:
- Create an account using your email only (instead of using the Facebook login option).
- Enter your name as 'Anonymous Contributor' and then contribute to the tilt.
- If you want to change how your name appears after contributing, simply click on 'Settings' on the top right of the page and re-enter your name as 'Anonymous Contributor'.
Note: your email will still be visible to the tilt organizer, so if you want to be completely anonymous, you'll have to sign up with an anonymous email address.
