When start forum 2009, rank policy system only activities then 2018 change forum rules rank up policy merit + Activities , I ask @theymos again any Possibility change forum rules upcoming future.
Why do you want the forum ranking rules to be changed again ? There is no issue and flaw in the current ranking system and therefore you will not find a big change, if there is any. I think perhaps the minimum requirement of ranking up may increase or decrease but the overall structure of ranking up will remain the same.
