Since UpViral has a contest rule - most points wins - it needs to show a live Leaderboard also. Perhaps on the share page or even better, if you can post a live points via email notification.
Yeah, this would be good, and most importantly when the contest ends, people can see the winners on a page publicly. Since it is a contest, it definitely provide more credibility that the contestants can view who the winners on a page publicly. Hope this can be implemented. It's definitely a simple add-on to the campaign. :)
