13, I joined when I was 10, a couple of weeks before I turned 11.
I was 1 year younger when I joined than when you joined: I joined December 16 2009, I turned 10 on January 3 2010.
oh man, when this december will come?!
Fast forward your computer time to December, turn your calendar pages to December, put some fake snow outside your house(well, only if it snows in your city) and it will be December. LOL just kidding!
