If you want to see your highscore(s) appear on the rankings please send a email to brainkiller007[at]gmx[dot]de and attach a video of your highscore where also the score, damage and multiplier is shown.
Or upload the video somewhere else (for example youtube) and attach the link. You can send that link also to Brainkiller007 via pm on youtube or on the WCR forum. If you don't have a video of your highscore you can also send a top-5 video or take a pic of your record.
In each case, if possible, please mention the score, damage and multiplier, the car used, the system used, and the (approximately) date the score was achieved. And of course your name you want to appear on the rankings and the country you are from.
For example:

Test Crasher
USA
Zone 1/Down Hill Demolition
9,876,543 x 21 = 207,407,403
January 1, 2014
Xbox 60hz (NTSC)
Supercar

Note: Scores/Records done on Dolphin or Emulators are not accepted anymore cause it is way too easy to cheat, which happened in the past.
