Until a few days ago, you could not create a poll with an end date pertaining to the current month. Meaning in November you had to create a poll with an end date being at least Dec. 1st, or your poll was automagically closed.
This has been fixed.
Another issue that I see now is that when you have voted, you should see the poll results at the top instead of still being served the poll questions. I voted yes. Fail.
