Spell Check for Twitter

If anyone has ever tweeted, you know what I'm talking about.  I hate to admit what a horrible speller I am.  I struggled with spelling for years and years and then technology caught up to my learning disorder and basically made it go away.  I have auto spell check on my email, spell check in my word and excel docs and I have spell check on my blog.  With all these advances I still find myself at times running into situations (hand written notes, Twitter,etc.) where I totally reword a sentence because I can't remember how to spell a bigger word I was going to use.  So today's idea isn't just for Twitter it's for everyone, if you have any online/computer application do our egos a big favor and plug in spell check.
