Even if you are not into the sports in Uber- Picks you most certainly know those who are fans or connosieurs. So the easiest way is to ask for their help when you want to enter those competitions. Then, ask them if they will like to compete on their own. Also, when you are around sports fans, in a caffee or a bar, you can casually mention that there is an interesting new gameplace on the internet, for real football/rugby/cricket fans.
