I need an official number of 181 so I can sign up? I can run lap times that will make me qualify but I can't sign up because I haven't got a number, But I can't choose one its just blank so will you please be able to add this for me?

Where can I see my qualifying times against other people's? Basically where can I see or how can I see if I have qualified? Probably a really dumb question but I can't find anything on your website?
