==================
I have a survey I use to collect names of individuals in our community who would like to be invited to other surveys we offer. 

Currently I export the response data from this survey (firstname, lastname, email) and periodically import them into my CPDB, so I can share them out to other surveys so they can be invited to participate. 

It is a bit tedious to do the export and import, and it would be great if there was a way to automatically update the CPDB via a cronjob... 

Is there a solution for this, or would I need to write a PHP script outside of LimeSurvey to accomplish this?

Plugin : using www.limesurvey.org/manual/AfterSurveyComplete
