As you may or may not know, you can now have your own Blog on these forums. To post a blog, simply click on "Blog" in the top menu bar, then go to "My Blog" and "Post New Blog".
To check a users blog, just click on the "blog" link in their profile. It's highly customizable, with RSS feeds and the options to subscribe to other blogs. You can also choose between three page layouts, two of which are completely different from the website's layout, one dark, and the other more light (see below)
