Important Update - a new improvement is being introduced to the system as of today, April 24th.
The moderator group has reviewed Rewards-related activity for the first 3 months of the year and has observed a number of unintended outcomes. As the result, in order to cut down on the number of useless posts observed in forums that started after rewards system introduction, a new requirement has been suggested by a moderator group.
The requirement was put in place today. From now on, users to have a minimum number of Kudos in order to progress through the levels in the GMAT Club Rewards and continue earning points. What this means is that members will not be able to reach a particular level, for example, Gold level without having at least 50 Kudos. If you are in this situation, your point earning will suspend until you are able to earn the sufficient number of kudos. If you are wondering how to improve your Kudos situation, consider posting helpful posts that go beyond chit-chat or simple question replies. Think about what you would give Kudos for and it won't take long until your efforts are rewarded.
The following Kudos requirements have been set in place:
1 Bronze 0 kudos
2 Silver 25 kudos
3 Gold 50 kudos
4 Platinum 100 kudos
5 Diamond 200 kudos
