To run another round of research with participants you've worked with before, set up a new study and ask us for a shareable link to send to those participants. Here's the flow:
Draft the new study you'd like your past participants to apply to.
You can remove screener questions and set Participant selection to Automated, since you already know who you want.
Choose to recruit from the Askable panel.
Submit your study.
Message us on live chat and tell us the study is for returning participants.
We'll send you a link to share with your past participants so they can apply directly.
This works both for re-interviewing specific people and for reusing a previous study's applicant pool.
