Crikey, that's a lot of personal info we want, eh? Well, not really. We need your email so you can prove you exist (and which you will use as your login), your name so we know what to call you, and a few sim racing specific things so you can race with us. Check the tooltips on each one for a detailed explanation of why we are asking for it, and which ones are optional.
NOTE that your login username will be your email, not your "Display Name"
