To be honest, I'm quite happy with our small little community of awesome people.
Besides, we have no advertising point at the moment. We're an Animal Crossing board, a game that hardly anyone is playing right now and if they are there are much better boards with tons of people that play it. Besides that, we're just a group of people that talk about generic things such as games and recent news, again there are better boards that accommodate that.
The only thing this board has right now is its small community of people that have been here since AC:CF time and we all stick around because we enjoy talking to each other, for new people, the "tight community" isn't something worth joining the forum for because they don't know anybody.
