2. Have other content besides just the forum. Look at this site, it has a frontsite that draws attention.
3. Have a specific enough niche-topic. People go to forums to discuss something. A hugely generalist forum will not work. Have some specific focus that unites all of the people who might be posting there.
4. Advertise the hell out of it. PM spamvertising is pretty tacky, but if you have other content you can usually find ways to advertise it. Note that this may cost money.
5. Get lucky. Duplicating the success of another board is nigh impossible. Some boards sink, others swim. In the end, most of it is up to your luck.
