If you know the name/number of your world, best place to find your world settings is right here in the forum. If you scroll down on the home page of the forum, you'll find all of the active worlds listed by generation. All of the settings are listed right underneath the world name.
Otherwise, if you want to know the settings of a world that you are thinking of joining, when you get to this screen
and click 'other worlds' you're presented with all of the world information of possible worlds you can join.
This is the only way that I know of that you can get information about a world's settings outside of finding it via forum. Problem is, you can't find out information about worlds you are playing this way - only worlds that you have an option to join.
