How about incorperating a spellcheck?
I am forever impressed at just how clever and knowledgeable people on this site are. Sometimes there are people for whom english is a foreign language ... and they appologise for their use of english; their gramar or their spelling. And then there are a very few, such as me, whether through dyslexia or some other cause, who's spelling etc appears sloppy or poor. Some websites do have a spellcheck facility. I know that a solution would be to type into word first and then paste it in ... but in reality, that just doesn't happen.
Just a thought.
