How do I get the [code] tag to display my language?
If no language is specified then the script will use the "preferred language" in your profile automatically. However, if your language is not currently supported then the script will auto-detect. You can override the selected language by using [code=_language_], but in the same way if it is not a currently supported language then the script will auto-detect. You can force auto-detect by using [code=?] or you can disable highlighting completely by using [code=*]. Both of these can be used in conjunction with specifying a language. For example, if your preferred language was PHP you could use [code=basic*] and it would display the language name BASIC at the top of the code block, but highlighting would be disabled; similarly with using ? for auto-detect.
Can I use HTML in my posts?
Unfortunately not. However, many of the features you would like to use, such as links, images, emboldened text, colours, and so on, can be achieved using custom tags. A list of the effects and the required custom tags are given in the table below. Please note that all custom tags must be in lowercase.
