In this post I gathered the complete information of activity by " last post" and compared it to activity by " last active" , the comparison showed significant differences. I did not show the " Brand News" since they have not made any posts and their contribution to forum is almost non existent. Also fresh full stats by rank can be seen in the end of post.
As before, I used last 3 month period and also looked as stats within this year ( from 1st of January to 24th of September)
Here are the number of users who have made posts in these 2 time frames by rank:

Including Newbies , there are total of 137122 users who have made a post in last 3 months, if we exclude Newbies , the number drops to 31211. If we take a look at how many posted within this year, with Newbies there are 313609 users and without them 46149 users.
Here is the activity by " last post" in percent:

The percent graph shows that there is very high activity from Jr.Members, this is because of the last rank requirement change- most of inactive users where demoted to Newbie level.
Further I compared " last post " activity to " last active" activity of users , this shows us that there is a significant amount of users who have been reading the forum and haven't been participating in the discussions. It was quite surprising for me , I was not expecting so many users to be reading and not posting across all the ranks, especially the high ranks. Here is the comparison graph:

Here are the difference between number of users who have posted and those have been " last active" :

Here is the data I showed above in graphs with full users statistics , which shows that right now we have a lot more Members than Jr.Members around


If you have anything you would like to see with this current data, i would happy to hear your ideas.
