Today is November 11, so that means...
We'd just like to congratulate our well-known moderator, author of thepcspy, and second-highest user by reputation here on a happy birthday.
Many of us have changed our gravatars to be Oli♦:
and last year, it was even better.
If you browse the user list, you can see all of the green faces symbolizing this happy day.
So, let's wish Oli a happy birthday, and the best of luck in thepcspy, here on Ask Ubuntu, the rest of Stack Exchange, and in life!
