I think you may be the solution for us but I just need to ask a few more small questions:
1) I could not find the option to export results from the sandbox, can you please tell me where i can find it. Also this reporting module is additional to the pro plugin isn't it?
2) Is there a limit to how many quiz attempts the database can store? (As with the WP Simple Survey plugin it cannot handle high volume and I was getting the following error: "Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 84 bytes) in /webdocs/school-hosting/goldcoastsouth/talloec/www/wordpress/wp-includes/wp-db.php on line 1449" - not sure if this was a hosting issue or a plugin issue. Richard Royal the plugin author does admit that the queries could be written better and less verbose.
3) All our test users need to be guests, it is too much to ask visiting kids to join up and become a member. At the end of the test our system will email them and their teacher the results of the quiz attempt. Also we need to store the results under the names given by the students (in a form they fill out after finishing the quiz) Is this possible?
For clarity, please refer to our quiz in its present form (http://thebeachschool.eq.edu.au/index.php/test-quiz-page/). We need exactly the same functionality plus some powerful backend features to report the collected data (which it appears you have in PRO version) - we are just unsure about the export features and storing user data without them being a member of our website.
If you wish to discuss this in a more private setting, please email me at firstname.lastname@example.org
Thank you for your time.
