The current poll feature is very primitive and poor in configurability and privacy settings.
In my opinion, the administrators should be able to decide who can see the poll results and who can not.
For instance I am currently running a series of polls to gather certain data about my members' preferences, and I do not want my competitors to get hold of the results.
But in the current layout, although I untick the "display the results publicly" box, even the anonymous visitors are able to see the results. I've got to figure it out after the fact, which was not nice at all.
I think the next release should have this feature improved to a professional degree.
