As an Administrator, you can add a timeframe restriction that will prevent Officers from creating Events on short notice. For example, if your timeframe restriction has been set to two days, Officers will not be able to create Events that will take place earlier than two days from the date they are submitting the Event.
Click the Admin button on the top bar
Click the Settings menu option in the sidebar, then select General Settings in the dropdown menu
Select the Events tab in the top of the main content area
Scroll down to Restriction timeframe create event and enter your desired timeframe in number of days, then click Save
Please contact email@example.com with any questions.
