Mandatory Informed Consent - by: tpartner

Place a mandatory yes/no consent question on the first survey page and then either:

1. Place relevance on all following groups to only show them if "Yes" selected and use Expression Manager to tailor the end message accordingly
2. Place a quota of 0 on the "No" answer so those respondents are screened out - manual.limesurvey.org/Quotas

Regarding "a text file(pdf, word)", simply put a link to that file in your consent question text.
