I have a difficult one. When user update the "Period Close Checklist", I need to add a user event to send an email to the Administrator. The record is PeriodClosingTask. I've looked all over and can't add a user event because the record is not available. Maybe it's another table. Any idea ? Thanks in advance

You can check the scriptable records reference for a suitable alternative. The only related thing I see might be the Period Close Journal

maybe not scripting, but can you do something with the system notes fields to fire an email on change via a saved search?
