And my forum is about computers,Windows and Linux. And also about forums and web hosting. That is creating a blog or website and using social network sites like Digg and Facebook. The disadvantage is that my forum is hosted on a free forum site and not on my own custom domain like this blog is. Which means that your site is not as secure as it is when you are hosting on a custom domain.As they can delete your site or forum any time. But if your site is hosted on your own custom domain they cannot.
