BBCode is a lightweight markup language similar to HTML used to add rich features to your posts and signatures. Opening tags are indicated by square brackets surrounding a keyword, and closing tags are indicated by square brackets surrounding a keyword preceded by a slash (/). For example: [b]text[/b] will cause “text” to be rendered in bold type.
You can use BBCode on a message page by clicking the “BBCode” tab found in the bottom-left hand corner of the message area when composing a new post. You can also use BBCode in your signature area when modifying your profile.
NOTE: Not all BBCode tags are implemented on this forum, and many supported BBCode tags are unnecessary because there are already automated in the editor toolbar. For example Bold, font size, etc. You can go here to learn more.
