The poll here.....

[Middle Finger]

That's exactly what is said, MF...I don't know if my vote was counted or not, I didn't pay attention to how many voted before me.

If it says:

You voted on this poll before. However you can change your vote if you wish.

And does not have that "Click here to see the results" line, then you voted.

You can just uncheck or check things to change it right now, then click the Vote button. You will notice that your newly checked or unchecked boxes will remain. Each time you hit the Vote button it modifies your vote.
