What this screen is
The first thing you see when you sign in, and the only screen you can rearrange. Your next match sits at the top - where, when, who, and how you have done against them before.
Arranging it
Press Arrange and drag the cards into the order you want, or use the Move to… menu on each one if dragging is awkward. Turn off anything you do not use. Nothing is lost by hiding a card; it goes back in the list to be turned on again.
Why some cards are not there
A card only appears when it has something to say. Waiting on you is empty most of the time, and the day it appears you notice it - which is the point. Cards about running a competition only appear for people who run one.
If it looks empty
A brand-new account with no fixtures has nothing to show yet. Once your club enters you in something, the cards fill in by themselves.
