Revisiting Partha's queryPartha's query appears to have some logic. A little deeper analysis of the facts, on my part, has raised a doubt.
Vandana shared this link in the magical surprise thread, referring to it as "this one in which changes were made", the Webmaster stated that "The issue with this approach is, if a top-ranked person stop visiting our site or stop recalculating his points, his rank will never change and will always remain the same". He went on to add that "Member Rank will be reset to 0 for all members who have not logged in last 90 days".
The number one rank is held by Pramod, but he hasn't posted anything from 01/01/2018 till date. How is he holding his first rank, if the 90 days rule is applicable?
