Overall this is just a bad idea, due to the facts of some people are not from America and don't speak English along with the forums are more for members of the community that keep coming back to harpoon. Some people just join random servers and want to play; take payload for example, people love that and when it's in quickplay anyone can join and if they had to be apart of the forums first servers would be less populated and overall not as good.
While I like all parts of the community to be active, I'd have to agree. Best you can do is just ask people to please join the forums.
