Its good for static websites, but no point for forums.

We automatically optimize the delivery of your web pages so your visitors get the fastest page load times and best performance. We also block threats and limit abusive bots and crawlers from wasting your bandwidth and server resources. The result: CloudFlare-powered websites see a significant improvement in performance and a decrease in spam and other attacks.

CloudFlare doesn't just make a preview of your website. It has a lot of other features.
