That was a big problem with automatic line breaks - when Max first tried them, they went all sorts of places where we didn't want them. Pene has a system that solves that problem quite handily, but it's still being tested. He has a check box that allows you to select NOT to have automatic line breaks in the message you're posting; and he also has a feature that lets you preview your message before you post it. No, you probably still won't be able to edit your messages once they're posted.
