As you have probably noticed your forum name colour changed to yellow today.
This is because you are now a full member and you can see more forum sections
During probation period the forum access is limited hence you did not see some of the posts.
Anyways, as for the forum activity we do have periods that are more active and more quiet.
The reasons for that vary. Lately, there has been a lot going on with solving issues related to COD elite clans, clan wars, and moving to COD only clan, just to name the few.... which spanned a lot of discussions in the 'behind the scenes' sections.
We are also still in the process of getting our normal scheduled events back on track e.g. pub stomping, special forces training etc... which usually increase the general forum activity.
As for the drop in the forum chatbox use...
I feel more and more people are shifting towards using the Line App for chatting.
The app is available on PC/Android/iOs devices and it's very convenient when partying up on PSN as well as casual chatting:http://www.clan4gc.com/t16690-line-id-s-please-post-yours-here
