Jeremy, here is a free spell checker that I always try to remember to use. It makes me look smarter than I am. This was a post from the RCU Administrator.
Good luck with your engine.

"To all those who have been going through spell check withdrawal I have located a solution which is better than the old checker.
This will work the best and is far superior than the old spell checker.
Download this IE browser extension. It is safe, it works and I have tested it.
You install it and then when you are in any text box you can right click to check spelling. It has user dictionaries and much more.
It is FREE."
