The one thing I noticed (and I could be doing something wrong) is that if the button is pushed to light then all stuff is light side leaning and same when I push dark. That being said, and since I have both light and dark gals. when I get on my dark gal, I push the dark button and when I get on my light gal, I push the light button.
I make the choices but it is as if I am not participating for the server but for my situation at the time. Not sure if that is how it was intended or if that means I am not participating. To each his own.
