I noticed that some people have a bunch of cubes under their username. While looking around, I clicked on the members link and found it was called Rank. Mine is (aparently) 4x4. I was wondering why I can see some peoples, but not mine. I can't seem to find an option to display it. Any suggestions?

Instead of going to the UCP, click your name under the "Members Online" section of the Sidebar. It'll show what your profile looks like to the rest of the world.

I'm pretty sure you can't view it in the User Control Panel.

The display of rank in the public boards was disabled to discourage people from posting needlessly just for the sake of inflating their post count or rank. The feature was not entirely disabled however as you can obviously tell.

That makes sense.

Just a couple of topics below yours - The ranks all the way to 11x11x11.
