Well, sorry, it's useless.
Let's see my case: I run an admin forum, a martial arts forum etc. I want my members to discuss about webmaster stuff and martial arts. Or finances, or whatever my main topic is.
I need to make them talk about THE TOPIC, not count to 3000, ban the user above and other useless things they can do.
Yes, your forum gets a lot of activity there because 1. you have the category and 2. it detracts them from the topic talk.
I am running my admin forums now with NO general chat section. Yes, it's crazy. I have the 'welcome' area and we do have a general webmaster chat for topics that go for both forums and blogs (since it's a blog/forum admin community).
Do you think anyone misses discussing what they ate last night or how Rihanna got beaten up again by her 'male'? Let's say we have better things do do.
If you want REAL activity in your forums, kill the games, delete the category and START THREADS in the specialized areas. Members are less inclined to start new topics, but do reply. Give them something to chew on and don't fill your forums with junk 😉
