HI Laure,
I am really glad to receive a reply from you,
The reason why I asked this query was whenever the rank get changed in old leader board in specific space it's always been motivation for me to work for the next level rank or a badge.The reason is simple instead of comparing with all the people of SDN (New gamification) its easy to compare with respective module
.
So its not easy to reach the top level at a single shot for every one(like me 
) for that need lot of efforts,knowledge and dedication is required. I strongly believe that this is the platform where we can get good knowledge,reputation and there is no second thought in it.
New gamificationchanges is really awesome, I really appreciate your constant efforts and each and every individual who are all working for this wonderful project.
we are also eagerly looking for new changes in gamification and ALL THE BEST for SDN.
Thank you very much for your precious time against my query.
Best Regards,
Krishna Kumar.
