Hi jdcrooner,
I'm sorry you reached a 404 error page. As you know, we just launched this new website, and many of the old links are no longer relevant. If you reached such an error page, it is more likely that a URL has changed than been removed.
Ninja IE Degriefer never had its own forum, it has always shared one with other modules here:
http://ninjaforge.com/forum/16-modules.
OK, to your question.. how to use Ninja IE Degriefer.
I suspect that because of its name, people think it is some sort of magic pill that will cure your site of its IE ills.
Not so. What it does is quite simple... it just allows you to hide modules from IE.
If IE has trouble showing a module on your website, then IE Degriefer will give you a way to hide the module from IE altogether.
I have created for you an illustration showing how to use it. Please find it attached in image and pdf formats.
Hope that helps,
Cheers,
Mark
