Change user in field who modified another field

Where can i find more information about automation?

Here is the Quick Base documentation from the site.
https://help.quickbase.com/user-assistance/about_quick_base_automations.html

In your specific situation - you'll want an automation something like this: 

1) Automation occurs when data changes in the table where you date field exists
2) Trigger is Based on Add/Modifications - and where that exact field is the field changing
3) Your action is to modify the specific record that was just changed (this would be in the filter condition) - and the actual change would be to copy the value of Last Modified By into your user field

Hopefully that helps get you started.
