At the moment the survey is either on or off. It would be great if there would be the possibility to give a survey different statuses like "open/online", "paused", "finished", etc.

The admin could mark the current status and respondents would receive different messages when opening the link like the survey itself in case of "online" and something like "The survey is currently paused/not active, please come back later" and "This survey has been closed, as we have reached the necessary amount of participants".
