now that i think about it, this would be pretty damn easy to hack on my own. though, it would be a nice feature to add to the next release anyway, so we don't have to rehack it. we could just add a couple of new buttons to the "make a reply" screen so the user can choose every time. for example, we could have "submit", "preview", "clear" and "attach file" buttons. this could be further refined with an admin option to disable / enable any of these buttons.
