Add user polls
We're opposed to mass mailouts (a.k.a. spamming), very much opposed to embedding "phone-home" metrics (a.k.a. spyware) in our product, and are reluctant to provide our customers an open public forum in which to whinge about our product (because happy customers generally say nothing, and no-one trusts a vendor-moderated forum). But we'd also sometimes like customer feedback on whether or not our software is doing what they want.
Our HESK instance is the one website that is frequently visited by many of our customers on an ongoing basis, and it seems to me that this would be an excellent place to pose simple questions with multiple choice or yes/no answers. It would be great if HESK could allow admins to create voluntary-participation user polls, that HESK would ensure could only be voted for once by each HESK user.
I expect that most sites would like to specify fixed closing dates for polls. It's probably also important for most users that poll responses are anonymous, which I guess is incompatible with being able to change your initial vote (something I like personally). We're flexible about both of those issues.
