The little gear icon at the end of the toolbar lets you switch between a visual editor and forum bbcode, if that helps? There's no raw HTML editor but I doubt we'll get one.
Another forum I'm on lets us use CSS (with certain limits) and as you might imagine it is incredibly easy to abuse when you know what you are doing (but it's a small, tight community and we just don't)... I can imagine similar problems arising when they let us use actual HTML.
