If you are referring to the posts counting towards the 'big game' status, then yes. All RP threads for the small game are tallied when a GM requests big group status. OOC/chit-chat threads are not counted in that total. This is to ensure that the RP aspect is what has the staying power and not simply the socializing.
So, for example, if there was a group called Darksprint, with 3 players, there would be a maximum of 6 threads. The GM sets them up as follows, and eventually they have the following post counts
[Darksprint]Setting info and characters 4
[Darksprint]OOC Talk 753 (chatty bunch here)
[Darksprint]The Corporate Offices 246
[Darksprint]The Docks 300
[Darksprint]The Hideout 57
[Darksprint]The Wastes 143
The 753 posts in OOC talk wouldn't count, so the game would still have 200 posts to go to reach 'big group' status.
