Well, tiny, tiny bug, anyway xD
On SMF 2.0, when I view the stats page and there's only one member, the Male to Female Ratio shows "1 : 1".
Unfortunately, I am male, and there are currently no females on my board (awh :'(), so this should read "1 : 0" instead.
Something is terribly wrong with this formula for calculating the ratio.
EDIT: After digging through the code vainly, I have realized that, quote from comment, "let's calculate this only every four minutes". So, four minutes later, it was updated. Shame, I wanted to contribute to the SMF 2.0 project.
Thanks for the report anyways :)
Its good to keep us on our toes ;)
