Unable to find "Edit Forum Signature" - Better Battlelog Forums #1704

I'm using Chrome, and the title pretty much sums it up. Where can I find this option?

Great job on BBlog, by the way! It's very useful and offers some cool options Battlelog lacks.
BBLog Center -> Board Optimization (click on the "gear" icon) -> Edit Signature.
Many thanks! I can't believe I overlooked it.
