In the forum is where the actual concern goes down about the game. If you want to support FeralHeart and be a nice member overall, bringing the community forwards you really do it here, since running around and yelling random things into the chats in-game doesn't really get you or the game anywhere.
This is not the case all the time, but I do believe the forum is a great way to actually get to know the active members/regulars of the game and what they do, even though the game has it's own ways to get to know someone more personally, the forum really has it's own ways doing so as well.
It takes that "lil" extra effort to logg on here and read/post though, but if you care about the game in any way you try to check up on it once in a while.
