Hi Will,
I am really sorry for the delay of this reply as it weekends for all of us here.
Something is really strange with your site as there are something that heavily cache the javascript files on your site and no matter what change that I made over the file /media/com_easydiscuss/scripts/toolbar.js, it will always load the original scripts rather than the change that I've made.
I even try to renaming toolbar.js to toolbar.js_bak and the file toolbar.js is still loaded on your frontend. Refer my screenshot here for a better view,
http://screencast.com/t/o7vq1ptv . I highly suspect that your server (not site) has some cache mechanism that preventing the javascript file from being loaded correctly thus causing the fix to not working on your frontend.
I hope this is clear enough for you and I suggest you to consult with your webhosting service provider regarding on this issue.
