Well, your forum is still very new. You need to spread the word and get your forum's name out there by advertising it. You could start by advertising it here.
I'd also recommend filling those forums up. Unfortunately, new members aren't going to post unless they have content to reply to.
You could do some post exchanges with our members, here. Post exchanges are a win-win situation where you get posts/threads on your forum, and so does the other member you're doing the exchange with. 😉
Too small to generalized and too narrow. Broaden your forum to include other games, don't just stuff all of them under one thread. Look over the zelda sites and follow them in their design. Wasn't there a TV show? Talk about that, also you must have content, no content no people, no people no content. This is where this place helps you in creating content.
If you make a Kirby forum one has to assume you're a Kirby fan. You should already have dozens of topics for discussion ready in multiple sections. On top of that, you have very stiff competition of already successful Nintendo/Kirby forums out there.
