Forums can and will always be a good place to interact with people who may be interested in visiting your website or blog, even if that isn't the sole purpose of your being a member of that forum.
Most forum owners nowadays make it a lot harder to promote your sites directly preferring instead to limit you to a backlink on your profile page. That isn't so bad because depending on how you engage with the community, there'll be a number of people who'll want to know more about you and will for that reason visit your profile page. And maybe they just might visit your site.
But if you aren't satisfied with promoting your website primarily via your profile page, what are some good strategies to draw traffic to your site from the forums you actively participate in?
