Fluid Surveys currently has the following limitations:
There is no integration with USask NSIDs. In order to send out email invitations to a group of people, you will have to import the list of users from a CSV file. This CSV file is best created in Excel, or you can use the Member List function in Blackboard Learn to create a CSV file.
Surveys should normally be completed in one sitting. It is possible to set things up so that a user can save their state and then resume, but this will typically require more capable and aware users.
There is no "export" capability for surveys. Fluid Surveys does provide beta versions for importing surveys from Survey Monkey and Zoomerang. You are welcome to try these features out.
Although Fluid Surveys maintains previous versions of each and every survey you create, if you delete a survey, it is gone, including all of its data and results.
Surveys can be made completely anonymous and secure. However, if you decide to enable IP tracking or Track Country, then you are reducing the anonymity.
