Thank you for your review.
However, we think that you might have misunderstood the way Joomla! extension works.
Our support team has investigated your site and found that you changed the tmp folder name without changing it in configuration file. So not only JSN Mobilize but also other extensions cannot be installed, and this can not be fixed from our side.
So please help to recheck and follow our supporter's instruction in support forum to make your site work smoothly.
Hope that you will change your mind with our support.
Hahaha, Thanks for that Tom.
We try to keep everyone happy. We are adding a new emailing submissions to teacher feature now too. So, instead of having to go to the site and login to check what the students answered, you can just check your mailbox as the teacher.
