Survey
Flying Fleet offers an integrated survey or poll system. To use it, you must first configure it via the "Setup" => "Poll" page. A poll can be valid for a given time, or without limit. Members can only vote once, and if they re-vote it will simply edit their vote. You may AT FIRST decide if the votes are anonymous or not, note that the information will be displayed on screen when members vote. Once the first member voted, you cannot change those settings anymore.
You may also use pre-existing tools like Google Form. To create the form you need a google account (free), but to answer you don't.

Create your form and then publish is from within Google Form. To publish simply click on top right part of the page "Publish" and copy the generated link. Copy the URL and paste it in the mailing tool of Flying Fleet, such that your users will be able to answer your survey.
