At first I wondered how to get into the contest. I wondered how you acquired the points. I wondered where was the button you pushed to get into the contest like you do with guild war or boss Pit or the mountain or challenges. sometimes I would get points in the contest and I didn't even know how.
Then I started doing to Simple Things. In the event section as you thumbs through the various panels you will see one for a contest that says it's coming up in x amount of hours and there is a little information window a little italicized letter i that when you push on it out pops an explanation of the event.
it gives you a rough overview what you were going to be wanting to do within the contest and how long it will last. I usually hold off on doing anything included in the contest until the contest
in my time zone, for me this means waiting until 1 am ,ugh, yes, in the morning, to start doing my dailies which is a sacrifice, since it sometimes takes a couple of hours, but I get an extra day's worth of winnings, because it resets at 5 in the morning.
but most importantly when the contest is underway, you click on the section labeled "points" and you go through it and see what you get points for.
there is no button to push to start or enter into contest, everything is automatically calculated as you do your dailies,
