Haha...check it

Go to Community Hall --> Ranking

Find the page where your name is on, for instance, I'm on page 7

In the top corner, it says "Results # to #+30" - on page 7, it's "Results from 181 to 210"

Then count how many spaces down your username is. As of right now, I am 10 spaces down. This is your rank, uncalculated.

Remember, the person who is listed first on top of the page you're on is # - that is, on page 7, it's 181... 10 spaces down is my rank, which is now 190.

Simple to calculate formula:
Go to the page where you're on. Look for "Results # to #+30"
Your Rank = # + spaces down - 1
