how do we make our writing glow?
If you're talking about on the forums, there's a toolbar specifically for text effects found right here:

The green backgrounded capitalised G on that toolbar is the effect that makes your text "glow"
The shadowed capitalised D on that toolbar creates a shadow effect
The moving capitalised M on that toolbar creates a marquee effect, which we don't really want many people using too much.
Disregarding the red box I highlighted, there are a few other text effects on the same screen, though you can just mouse over them to see their descriptions ;)
