Go to Polls -> View the polls. Cast a vote on a open poll. Once casted, go back to the polls page. I still see an icon that says I need to vote with a blue button.
After I had cast my vote, I want to know in someway that I already voted. So if the person already voted, the button should be something else that signifies they already voted, but also that they can change their vote if they choose. Either use a different color button or a different icon unless you think of something better.
I think you guys updated how Polls work / are seen a while back. I was wondering -- is there a way to look at the list of polls, and tell whether or not I've already voted for something?
