Another stupid Question about studies / Status Visibility : Invite only / What does this actually me

Hello guys,
I have another stupid question about studies.

I have created a study with the visibility status : Invite only

Now I wanted to invite somebody to this study.

The system shows me then a warning : Please only invite people you know and who actively want to join the study.

Does this mean that an invited person can modify my study ?

I don't want that. I want to be the only one who can modify the study. The invited people should only have the right to look at it and nothing else.

Can I kick out invited people from my study whenever I want ?

Thank you for your answer.

I think you actively need to set invited people to "contributor" if you want them to be able to change your study. Inviting them only lets them see the study.

You can indeed kick out invited people whenever you want.

Also, your questions are not stupid.

Thank you very much.

Everything was clear after I invited one person. Then I saw my options.
