Hi, I am wanting to link two surveys together. After the initial questionnaire the respondents have two weeks to take part in an independent task, following this they will need to take part in the second questionnaire. Is there a way for participants to be notified exactly two weeks after they completed the first survey (this is an important aspect) via email or elsewhere to complete the second. Even if we were to email participants individually with an invite link, will qualtrics show us the date they completed the first study?
