I agree, topsites not always work.
Good keywords, contents, design and members will help you to get more members.
They will recommend to others your site for these features, most important, activity. If your forum isn't active, forgot about getting new members.

People is currently paying for referring people, or post in their forums certain amount of posts. After that, if they liked your site they will stay.
If you have good contents, and people talking about interesting things, you will have many people in your forum.
