I have found the great thing since sliced bread! It’s called SpellingCow.com. I know there are probably other sites out there that do the something, but this was the first one I found.
From there website:
SpellingCow can spell check as you type on any web page. Just add one line and your website will have the best spell checker on the net! You may also run SpellingCow on any website you visit via the use of a favelet.
The best part about this it that you can use it on just about any site on the net. So no more looking like a idiot on message boards. I can just spell check on the fly.
Moo! SpellingCow.com I wish they had a Grammar Cow.
