Hello Jaymz,

I am really sorry for the delay of this reply as it is a weekend for us here.
I have checked in your reply side in Easydiscuss, it seems like work fine for me (user - administrator -> http://screencast.com/t/U0ECvvlF7j ).
I guess that you didn't set that user group permission, see my screenshot : http://screencast.com/t/0GLOqSAiAlX
And i already help you set it, can you have a try login as registered user and see how it goes?

Regarding with your another issues : when click that article button then hit "Error: 500 - JForm::getInstance could not load file"

It seems like this article button didn't work fine in Joomla 3.2 only, i believe that you also have try this article button in previous version of Joomla and that is work fine right?
The article button is actually from joomla editor xtd plugin, and the Easydiscuss only just display the editor.
I have tried to search some resource from google, it seems like not only JCE-Editor hit this error, even JCK-Editor also hit this error, you can view my reference link below:

Hope this help.
