I think I didn't understand it before just now. The point is to make a text parser version of messenger which doesn't allow you to post before it's grammatically correct, right?
Would be lot of fun to watch people drag their hair out over not being able to post, but if they'll learn to write correctly, I doubt. It's hard to learn the correct spelling, when nobody tells you what's wrong, and what the right word is.. But now I'm just being annoying. For comedic value, I say do this on all schools, and let the kids chat in the English classes..
