We would like to be able to schedule the closing of online registration for our calendar events. Right now we have to close them at 5 pm at the latest (while someone is still in the office) but we would like the option to automate this and close them at 10:59 pm central time (in alignment with end of day for BBMS on the East Coast). We would also like to be able to automatically add a custom closing message when online registration closes that provides event contact information as well as a link to the event donation page for those that can't attend but would still like to support the event.
