My online game has an online community as well, which currently is in two places since we are getting ready to move to vBulletin from our own propieriaty software:

Current forums:

New vBulletin forums:

You don't need to register to post but you to get into the game to understand the forums you do, you just go to:
http://www.darklights.com/ambar/create.html and sign up, I will delete you afterwards if you contact me here or somewhere else.

The community is the online community for the game Ambar, and they are players and sometime just people who like to post their who once played the game or are going to start soon. Our target audience is everyone, but especially 12-24 year olds.

In terms of success, I dont have specific statistics for the forum, but the entire site gets somewhere between 10,000,000 to 15,000,000 pageviews a month and 250,000 to 500,000 unique viewersa month, and I presume at least 33% of that is from the forums or so.

Anything you would like to say is good, I would love to make the community better because that is what the game is built on.
