The two numbers on your profile
This is the most common mix-up for newcomers, so let’s start there:
Rating is skill; ranking is harvest. A high-rated player who hasn’t played in
six months has a low ranking — and that is correct.
A ranking is not a competition. You don’t sign up for one: it is computed
from the matches you already play.

Where your rating comes from, how ranking points work, and what moves each number.
