I've seen some recent attacks of some posters regarding spelling, and as a dyslexic myself, I thought I'd give some assistance.
If you are using internet explorer then go to this link: http://toolbar.google.com/?promo=gdl-tb-en .
It is from Google and places an browser spell checker in your task bar. After you have completed your post, click on check, and it will show you your spelling errors, with suggested words.
And its FREE.
