Might I make a suggestion? Is there a way to post All the groups/guilds/chapters/whatever that have a facebook page/group and the link to it here on the forums? Another great thing would be to post a note on the Tribe of Judah page with the same information.
I am a HUGE facebook user, and I have "liked" the Tribe of Judah community page, but I never see anything coming up about it on my home page. If it's one of those pages that you have to visit in order to know what is happening on it, it will never be used the way you would want it to be, the activity will remain low. Given the right set up, it might be used more frequently. Right now it is a Page - it's designed to be similar to an individual profile. And just like an individual's profile, it will not have that much interaction unless the status creates some. With a Community Page - it's too much effort to use it, it doesn't engage me in anyway, and it has very low visibility. It's not really designed to be interactive, it's designed to be informational.
The reasons I like a group page is because it shows up on the right side of my facebook screen, it shows when something was posted with a little number (similar to the inbox), and anytime I want to check it out, I just click on it and BOOM, I'm there. I can also be updated via my email if I choose to be. There are some down sides to it as well, but that's just my thoughts from a user side.
Another thing about using facebook, some people that won't use the forums will use it. I know of three people right now that do not use the forums, but would interact on facebook. I think it's a preference and one probably wouldn't take away from the other. They server two different kinds of people. Some want to give information and interact with others (forums) and others just want to get information or share in a quick way (facebook). It is also much easier to share pictures and stuff on facebook than it is here. In addition, facebook is a quick look thing, for instance, I've been working a number of days, long hours, I haven't had time to go through the forums as much as I want, but I would take a few minutes to check out a facebook page to see what might be happening quickly.
I'm really not for or against a page - just pointing out some thoughts about one. Again, I'm still trying to figure out what a group would be used for that would create an interaction on a daily basis? The current community page seems to be used as a sort of bulletin announcements, such as deals, new games, etc - not so much as interaction - twitter would be better for that.
One thing that could be done to encourage of both the facebook page and the forums is the daily scripture could be posted with a link to the forum thread. It wouldn't require too much time on the writers part, as it's just copying the scripture and a link onto the facebook page. It would bring the activity level up on the facebook page, thus making it appear on more people's home pages - as well as drive traffic to the forums.
If there is something unusual or cool happening in one of the games, a little blurp with the link to the thread about it here on the forums could be posted on facebook. This might encourage a little bit of cross interaction. I have no reason to look at the games I don't play, but maybe someone is posting about a cool achievement, or like in Terrari or Minecraft it could be a big project. Since I'm not familiar with the other games, I'm not sure what could be posted. Again, the main person for that game could easily make this posting without much added work. If this is done frequently enough, people may start to make such posts on their own. This would also create traffic both on the facebook page and the forums.
Just some quick ideas and thoughts off the top of my head.
If you should decided to put one up, I'd be willing to help out with moderating the page. I've done several of them. I do work, so I couldn't monitor it all the time.
