Hover Link Color

It's a simple text-shadow:

On PunBB this would make all links glow:

PunBB:

Code:

.pun a:hover {
color: #8B0000;
text-shadow: 0 0 0.7em #8B0000;
}

You can use the text-shadow: 0 0 0.7em #8B0000 under any selector on your forum to make the letters that selector applays on glow.

phpBB 2:

Code:

a:link:hover {
text-shadow: 0 0 0.7em #8B0000;
}
