In a brief response to the SPELL CHECKER, it probably works fine on most of these postings. However, the problem I notice to be very common is that the words are spelled properly, they're just using the wrong words. Example, I see very many applications of improper usage of "they're" vs. "their" vs. "there" all too often. Oops, THERE is another example... to vs. too vs. two.
Okay, just thought I'D throw my too sense (I know)in!
