Since the thread title is Uber for newbies, can someone point me to a users' guide? I mean how do I request a ride (with a Windows phone)? After signing in, I get a map with my location pinpointed and a menu icon at the lower right. None of the menu options are "request a ride". What do I do triple tap the pin while picking my right nostril and whistling Dixie?

I know it is bad form to design a user friendly interface these days. Uber's help is useless.
