In case no one has let you know, the forum editing mechanism has problems, at least on IE9.
If you enter enough text such that it needs to scroll, it will continually reset to the top scroll position, such that you can't see what you are typing unless you stop and manually scroll to the end.
Using the mouse to position the caret at the end of the sentence was also problematic. You had to be right at the end of the word, or it would go somewhere else.
