CPhill decided to take a short break, I think he will come back this fall.
Once you do not log on for a certian amount of time your account is not posted on the leaderboard anymore.
Logging in again will repost onto the leaderboard.
Please clarify by "didn't work"
Did you mean you aren't on the leaderboard?
Leaderboard only shows the top x amount. You aren't in that amount, I can tell since your point level is around half of that when I got onto the leaderboard, undoubtedly after so long the bottom point location has moved up significantly.
Click on the down arrow of the Leaderboard list.... then look at the top of the list : CPhill + 111455
