THE SEA KAYAK FORUM currently integrates Google adwords into the site, on the top of each content page.
You can sign up to google adwords, and specify that your ads are only to appear on seakayakforum.com or you can implement a more generic marketing strategy, so that your ads may appear on occasions.

There is no minimum spending requirement - the amount you pay for AdWords is up to you.
Google provide keyword traffic and cost estimates so you can make informed decisions about choosing keywords and maximizing your budget. You also pay only for results: You're charged only if someone clicks your ad, not when your ad is displayed.
