Since the OP has already asked, I no longer need to ask about the number of accounts that I see that do not have the same amount of activity as the number of posts seen in each profile.
After the first 14 posts when you register an account on this forum, the activity will start counting 14 every 14 days. That is how it is working and I have not seen any difference at all. You can start to monitor some accounts about this to confirm if what you are saying is true or not, I do not see it to be true, activity counts 14 every 2 weeks.
After 14 days after we made the post? Is this really the case?
Now the number of posts I have made totals 25, not including this post. Usually I don't have to wait long to balance the number of activities with the number of posts.
It seems like the forum system is working well regarding updates.
Do we need to keep bothering ourselves on what had already been well explained here
about how merit and activities works, why not read it very careful and understand the process instead of arguing what is not, am very sure of it that if you don't meet up with the required activities needed for a particular rank there's no how you can be able to rank up even when you have the required merits for that rank.
