Display referral goals to the user

Some of my contest participants have asked to tell them how many points the leaders have. I think it would be nice to show each one what's their place in the contest, or the top 5 contest participants. I think that would also encourage them to work harder for referrals. Also, if I could somehow show them how many points they need until they reach the "next goals", too. Like I could have a goal for 500 points, for 1000, 2000, etc. And they should be able to see what prize they get for that goal, too, when they click on it.
