The Export function will export the schedule (events database _as a tab delineated file, which can be pasted into a spreadsheet. Any game results can be extracted and saved for backup, or processed using basic spreadsheet functions.
It is possible to corrupt a schedule using edit functions, to the point that it is easier to start over with a clean database/schedule. The DB Maintenance page can be used to reset the schedule/events database to either a specific time or to a named backup image. For example, if edit changes go awry at 9:30 - 10:00 am, it is possible to reset the database to what it was at 9:00 am. Previous changes made after 9 am will be lost. Most DBs have a named image in which no scores have been entered.
