There is an option on the settings page that lets you choose between different skins, which are supposed to change the look of the site, I assume. However, it doesn't seem to work. It's not really important, but I thought I should bring it up anyway. It would be cool to have some kind of dark "night" skin after all.
I'm using Chrome on Windows 8.1.
By the way, this is probably the fastest site on the internet. I'm on super slow internet right now and nothing really loads, not even super basic stuff like Gmail in html mode, but this site works just like always.
