You're right. I was going to make a note of that for myself in this very thread, but I was at work and it slipped my mind.
Anywho, now the form has Dark Iron Dwarves, Lightforged Draenei and Void Elves nicely added. Also the Demon Hunter class that was still missing after all this time.
(BTW, Shevron, all admins are able to edit the form in ACP under Forums -> Customizable Form Builder)
