I see it! Installed and it's working right now. I'll have to look at my settings later.
In the meantime, I wanted to share how we style external links (seems to be a convention), adding a bonus hover effect. Edit as you see fit.
==========================================
a.ext-link, a.ext-link:link
{
background: url(images/external.png) no-repeat 100% 0;
padding-right: 13px;
}
a.ext-link:visited, a.ext-link:visited
{
/*color: purple;*/
background: url(images/external.png) no-repeat 100% -100px;
padding-right: 13px;
}
a.ext-link:hover, a.ext-link:active
{
/*color: red;*/
background: url(images/external.png) no-repeat 100% -200px;
padding-right: 13px;
}
Here's the image referenced above.
