In my profil, they are a difference between post and activity. I think activity is important for the status member? it's true?
You can see it here: https://bitcointalksearch.org/topic/forum-rankspositionsbadges-what-do-those-shiny-coins-under-my-name-mean-178608
For the next rank you need 60 posts/activity
The activity updates every 30 min.
You can have maximal 1 activity point for every day you are registered
thank you very much, finally for update the status member, it's the activity the most important and no the post number.
The activity number is determined in this way:
time = number of two-week periods in which you've posted since your registration
activity = min(time * 14, posts)
Activity is updated every hour.
