How can you extend the trial date for a school who requests more than 30 days?

When creating the order, click on the Subscription End Date field, and you’ll see a little tool-tip with instructions on how to back out, level by level. Keying Esc once will allow you to edit the year, clicking it twice will allow you to edit the day, and clicking it three times will allow you to edit the month. Clicking Shift-Delete will clear the field so you can enter from the beginning.
