How about auto correction on spelling. My 'Y" sticks and is omitted sometimes in a word. I see many spelling errors in posts (probalbly people like me who "hunt and peck" the keyboard), not to say people don't know how to spell, but their message is sometimes not as clearly understood when it contains several errors.
This is like a notepad window, instead of a document window.
Maybe have an edit button which is always available for you to correct posts when you notice a mispelling.
Just a suggestion. I get a little embarrassed when I reread a post, and I see stupid errors which could have been prevented if I had proof read before posting.
