Form control in this context saves every keystroke as you enter it and allows you to restore partial posts after recovering from a crash.<br/><br/>  This and similar was a lot more important back at LiL, where Lissa’s complex multi-character code was fragile, causing post and website crashes. I’ve not had to resort to the one I was previously using which I don’t like for reasons we don’t need to discuss. Should work on websites like Facebook where we enter text into like we do here.</span></span>
