Did you know that you can have a form "expire" at a certain time?
Very similar to how you can have a form become inaccessible after a certain number of submissions you can also have a form expire at a certain date. This is great feature to use for Parks and Rec events that have deadlines on when submissions can be received. You can set a date for the Event Form to expire and then after that date no one will be able to access the form and submit their information.
Can you think of an event in the future that has a deadline for submissions?
