The reason you can’t see the points is because the standings have yet to be updated. It’s usually done a day or two after the race. I’m sure you know how points are scored as it’s on the predictions page.
To find yourself easily, press CTRL and F and then type in your username, and it will find you on the page. Saves scrolling through.
Maybe it’s been mentioned before, but I find the predictions submissions page could do with some form of postive feedback that the submission was made – at least for me pressing the Add Prediction button initially seems to have no effect so I try again. Eventually the page reloads and a few minutes later I get several emails, showing that the submissions did work.
Of course, it could be me, but without that positive feedback, how do I know whether the submission worked or not? Fine if I’ve got time to wait for the confirmation mail, but if I want to go out or qualifying is about to start then it’s a different matter.
