I wrote a wall of text (It had to be done.) and it posted an empty comment. It shows up fine in my personal list of comments made however. Using the Edit button will show the comment in the edit box.
Where you had "Insert Topic" you had angle brackets. I replaced those with regular brackets. Looks like there is a bug when you enclose text into angle brackets.
