I may be being thick ... But ... How do you select riders?
Will, I was a bit stumped at first too - it's not immediately apparent!
Once you've registered and logged in, there's a rectangular black box that says "enter now" somewhere near the top right of the screen (near where it says 'log out' etc...). Click on that and it should take you through to a screen full of drop down boxes where you can select your riders.
