Though I've only been here a relatively short time, compared to the First Ones, I don't think that I've seen the forum die down in that time. The community is small compared to a couple of other places I inhabit, however this is when I can pull out the cliche "size doesn't matter". It's rather uncommon for me to come across threads that don't have any replies (in the non-hosted forums at least) - if you stick around you will get a response. In other forums with more traffic and users, there remain plenty of unanswered questions and unchallenged comments. And most of the time, I'd rather receive one or two responses in this forum, than a dozen in another, because the quality of posts here is quite high in my experience. Even the nonsence replies are of good quality.
Of course, as a community moves on, the First Ones will begin to move away, called onto other things. While it's not always a joyous occasion, it does happen. However it doesn't mean that they're dying or dead. New people comtinue to find out about the game, play it, enjoy it, wish to discuss it, find HLP, and become part of a happy community. To use another cliche, the forums are what you make of it. I for one don't plan on leaving, although I don't actually contribute to any projects (though I wouldn't object if there's a niche I can fit into somewhere), which I think was the focus of the original question being asked - I've forgotten after only 5min.... looks like time's up.... have to stop writing before this turns into an aimless ramble....
