Hi everyone,

I use oTree to run a large scale survey (few thousands participants). The survey is a bit long (40 minutes) and might require participants to look for some information (it's a survey for experts) so I want participants to be able to answer the survey in multiple times.

Would it works if I create one room with one large session (e.g., 10,000 participants) and create participant_labels with use_secure_urls, and then distribute the individual links for each participant_label?

To participate in the survey, participants will have to register through ORSEE (the link to the ORSEE registration will be the unique link I will share in various communication campaigns). So, once registered, I might be able to send individual links to each registered participant on ORSEE.

To monitor the survey, I could create two variables: participant.started = False/True and participant.finished = False/True.

Would that work for you?

Thanks for your help,
Louise
