After noticing a few links that weren't set up quite right, I thought I'd let you have a read of this to help, which covers the basics. BBcode is allowed on this forum so it's best not to turn it off in your profile
>>> Guide to BBcodeWhat is BBCode?
BBCode is a special implementation of HTML. Whether you can actually use BBCode in your posts on the forum is determined by the administrator. In addition, you can disable BBCode on a per post basis via the posting form. BBCode itself is similar in style to HTML: tags are enclosed in square braces [ and ] rather than <and> and it offers greater control over what and how something is displayed. Depending on the template you are using you may find adding BBCode to your posts is made much easier through a clickable interface above the message area on the posting form. Even with this you may find the guide useful.
