TGML stands for Tecumseh Group Markup Language. TGML is proprietary to these forums and allows you to format your posts, enabling bolding, italicizing, and so on, as well as typing in color and changing your text alignment (center, right alignment).

You have the option to process TGML in your posts, allowing them access to bold, italic, text colors, etc., or you can turn TGML off to ignore TGML markup commands and output your post as you typed it.

Below are the available tags, and sample usage...

You can use the [ignore] tag to let TGML know you don't want to mark up a section of your post.
Special Programmer's Note:
A small minority of members, posting certain types of programming code, experience conflicts with TGML. If you are posting code, please check your output to be sure it outputs correctly. (Especially check the formatting around URLS and array subscripts). If your code does not look right, try surrounding the problem portion with the [ignore]..[/ignore] tags to ignore TGML, or use the checkbox to disallow TGML from your post altogether.
Final words
You can also combine the TGML tags:
[color purple][b][i][u]Bold Italic Purple Underlined Text[/u][/i][/b][/color]
You can also combine the TGML tags:
Bold Italic Purple Underlined Text
