Automatically deactivate survey when a certain number of participants is met - by: tpartner

In contrast, if I first begin with a screenout or just leave the survey, it should not count.

I didn't test with screen-outs. You'll need to do that.

Do you know where I can find the information whether this feature is applicable for my version, too?

Test it. You can see the current quota counts in the "Completed" column of the "Survey quotas " screen.
