How I can check my poll

I think you just can check its status if its pending or published by clicking "My poll" in play tab. :)

Go to "Play". You can check the details of the polls can be seen in "My Polls". Just check it once.

If you have submitted it only yesterday, forget about it for another 15 days or so, that is how much time is required to approve and publish a poll. If approved or accepted, whatever the status, you will be notified of it.

B) Yesterday I had submitted one pole, How I can check its results?

Actually, status do not appear in My polls. If is approved or rejected, whatever the status may be, you will receive a mail. But it takes longer.

You should have posted it in doubts and query so admin would have replied to you about your poll. However, the polls take a few days before approved so this thread is closed.
