==================Hello All,I have a survey that I want to use as a closed survey under the following conditions: • There will be 200 users who want to use this survey. • I do not want to allow users to modify the survey. • Each user will create their own participants who will fill out the survey. • I want each user to only be able to view the responses from their own participants. The only solution I found for this is: 1. I collect the user's name and email address. 2. I create a copy of my survey. 3. I create a user with the "Use internal database authentication" permission only. 4. I assign the survey to the user with the following two permissions: create participants and view responses. However, doing this several hundred times would be a lot of work. What do you recommend for this process? Thank you in advance for any tips. 

This system can not be done with LimeSurvey only.

Have participant who can create own participant can be done with plugins.

• A participant (manager) can create token for a group : gitlab.com/SondagesPro/TokenManagement/TokenUsersListAndManage
• Allow reload response of simple user by the manager : gitlab.com/SondagesPro/coreAndTools/reloadAnyResponse
• Allow managing response by manager : gitlab.com/SondagesPro/managament/responseListAndManage or/and gitlab.com/SondagesPro/QuestionSettingsType/questionExtraSurvey
