> And just that quick, another thing I don't understand pops up. On that last post, I punched the preview button and read through the stuff I had written. Oops! I found a minor grammatical error. So I punched the back button to go back and correct it. I got a blank "Post a Message" form. The forward button put me back on my post, but wouldn't let me correct it. So I punched the post button and sent it on its way, bad grammer included.

Does this usually happen? This means, probably, that your browser's cache isn't set up properly, as the page with the post form, along with what you typed into it, expired as soon as you hit the "preview" button.
