Currently we are only able to set a closing date for forms. However, for some applications it is crucial to have a number of maximum responses instead. The logic is super simple. Apart from registering a maximum_responses value one only needs to check for it whenever a response is given:
If responses >= maximum_responses:
close form
That would be a great little feature!
PS: Apparently you can set the form tag for this thread, but I can't find the option. I apologize.
