The glow tag doesn't show you a preview.
The preview worked for me.
What I meant was that it doesn't
glow in the
WYSIWYG mode. You are correct that it does show up in the preview and in the finished post.
To see the WYSIWYG mode, click the "A" button under the "Change Color" field. You can turn it on by default in your User Profile--somewhere or another.
I'm having a little meltdown right now, or else I'd do a tutorial. I was walking away from the keyboard feeling good about the upgrade two hours ago. Then I found a bug in JFusion's SMF plugin. The SMF developers have changed many of their field names. I think I've patched the plugin--time will tell!--so it's time to try the "walk away feeling good" routine again.
