You’ll probably need to jump start things, so I’d look to advertise…everything from Google Adwords to Facebook to LinkedIn. I’d also look at traditional advertising, too.
You’ll also want to make sure you do SEO, including having a blog.
Tweet out (and share through FB) some of the best threads, driving traffic back to the forum.
Consider adding a leaderboard, too. Seems to get people active!
