How about including NotIcons.css in a way that unregistered users/visitors can see the icons as well?
I've made a test with NotIcons.css and noticed you can only see them, when you're logged in at WordPress.com.
Wouldn't it be fun if we could play around with the icons in our posts/blogs? I don't know if this is desired at all but if yes, how about adding more helpful icons.
The blog I need help with is iqatrophie.wordpress.com.
