What module does the Event data get posted?

Probably a basic question for most php programmers but I can't find it.

When I hit Submit on the Event Form Add or Edit, I want it to also update another table in addition to the events_main table.

Is it the TWIG module? 

Any ideas on how to fire off another table update as soon as the Events data writes to its table?

Appreciate any advice on this.

Nevermind. Found it.

The data gets saved via the _addForm function found in inc/classes/BxDolTwigModule.php . If you want to modify it, you will need to copy that function into modules\boonex\events\classes\BxEventsModule.php then put your code after the following line :

$iEntryId = $oForm->insert ($aValsAdd);

If you modify it in inc/classes/BxDolTwigModule.php then other modules that uses the same function will be affected.
