@Nick Ashley,
Doesn't seem to be working yet.
Nothing in the "reply" box.
I went to the homepage, and there was nothing in that text box.
I then clicked on "ask a question" even though I hadn't entered anything, which brought me to the "there was a problem" page that had more info. The "Show BBCode Editor" link was there (bright green font), but nothing happened when I clicked on it.
Took a screen shot if you'd like to see it.
