- * @todo use quickforms for the forms
- * @todo check if the user already filled the survey and if this is the case then the answers have to be updated and not stored again.
- * alterantively we could not allow people from filling the survey twice.
- * @todo performance could be improved if not the survey_id was stored with the invitation but the survey_code
