Hand-writing's fine, if you don't mind typing it up later. You wouldn't be the only writer to do things that way. But seriously, you need a spell-checker. Badly. Very, very badly. Even if you're severely dyslexic (one of my last bosses was, to the point of illiteracy) there are software programs that will help figure out what you're trying to say, or you can use Dragon to dictate to. It'll get some words wrong, but far fewer than you have wrong in just that small post.
