Under "Features" for wordpress.com it says:
To keep you from looking too silly, we include an inline spell-checker that makes it easy to proof your posts.
But I don't seem to have one and Dr. Mike said on the forums that there isn't one. So shouldn't you remove that as a feature? If there is one and I just misunderstood the forum discussion please tell me how to access it. All I seem to have is "lookup" which is a pain.
