Questions about the study, deleting a submission without your code, or anything else. Tim reads every message himself and usually replies within a few days.

Lost your code? Choose “Delete my submission”, and tell us roughly when you took part and your answer to the role question.

Please don’t include your private code or anything confidential.

Your message, email and name (if given) are kept apart from any submission (except that a deletion request is used to find yours), read only by the researcher, and deleted once handled, or after 90 days at the latest. How messages are handled
