I like a forum with a healthy, active number of users, but small enough that you start to recognize names and maybe make some friends. Basically I like a community site, which is what Forgehub is. A community you can actually start to recognize names, people can start recognizing you, and you make friendships over time. A community is helpful, and people know where information is. Forgehub is a great community. Bungie.net isn't really organized well like Forgehub is, and the main two H3 forums(including optimatch) just move too quickly and repeat topics too frequently for me to hang around.
