Hi,
sorry for late reply,

you can build a simple plugin based on our skeleton plugin, follow these steps:
- Download, install and enable our skeleton plugin (you can download from http://docs.easy-profile.com/index.php/article/triggers)
- Open file /plugins/jsn/skeleton/skeleton.php
- Remove examples frunctions like: triggerFieldAvatarUpdate and triggerProfileUpdate
- Create your function like this:

public function triggerProfileUpdate($user,&$data,$changed,$isNew){

		if($isNew)

		{

			// Here code to launch your query

                        // all new field values are into array $data

		}

	}
