Oh boy... the Forum software is not mine, it is vBulletin. For several (good) of reasons I have chosen to remain on the current version. I don't have IE9 yet. I'll give it a try and see if I can repro your difficulties.

Just to be clear, you could not post to the Comm Center at all? Or you could and there were extra blank lines? I'm not too clear on what your problems are. It might become obvious when I try to use it!
