Most of us, I guess, have a word processor that includes a spell/grammar checker. I use Word to vet my posts. The problem is that the same bug previously pointed out, namely truncation of text at punctuation marks of text copied and pasted from a webpage, also holds true for text cut and pasted from Word.
You guys do realize that Firefox has a built-in spell checker, don't you? Also, if you install the Google toolbar in either Firefox or IE, you get the Google spell checker as part of it. There are also alternative add-ons for FF.
There's no reason to use Word or any other word processor.
