Voting?!? (I'm so confused)

I have a few questions regarding voting if anyone knows please reply.

How many times can we vote through voot online?

I vote and it says "go back to voting", and then it let me vote over and over, did all of them go through or only one vote counted?

If you vote one day can you vote the next day with same email ID?

What are the official ways of voting?

And last but not least, which is the most reliable source to seehow the results may look?
