If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

What match purpose did you understand?
Which participation rule was unclear?
What choice was missing?

Author notes / illustrative keys where applicable:
1. Check what attendees think the matching activity is for. An activity purpose should not imply that every match will be relevant.
2. Identify the participation rule that remains unclear.
3. Use missing choices to explain available options without collecting personal profiles.
