User story: the possibility to create polls was a request from the Warsaw group. As an alternatie they’d like to be able to collect member’s e-mail addresses. Once they even did a little hack by creating a dummy profile so they could use the review membership feature and get all the people in the group to vote on a specific question.
My comment on this idea is that it would definitely be useful! We in the Karrot team have touched upon this previously. There’s a lot of examples out there from different platforms on how to go about (including what you see below) in designing this feature. I think the possibility to define the answers on the polls gives more flexibility, instead of having fixed predefined answers.
