Is there any chance of changing the order of the save/preview/submit buttons? Every time I go to post I instinctively click on the left button and save myself a draft which I then have to dig out and post properly. I know I could learn to read before I click, but failing that, could we 'hide' the save button a bit better, or even get rid of it altogether? Most forums don't offer a draft facility and I don't think they're any the worse off for it, if you're worried about losing a big chunk of text while posting then you can simply Ctrl+C.
...and yes, I did just click the damn button again while trying to post this. Fail.
