If you want to make your text Glow, use the Green "G" button in the top post menu bar. In the popup enter the colors, Red, Yellow, Blue, Purple, etc. You will then need to enter the text you want to display.
Edit: Unfortunately, this only works in Internet Explorer.
PHP Code:
[glow=color]ENTER TEXT HERE[/glow]
Replace "color" with the color of choice and it should show up like the examples below.
Red
Green
Yellow
Blue
Purlple
