i've done a hack to allow the admin to control, via the CP, the look of the POST fields. for example, you can specify in your CP to make the input field text red, Verdana, bold and have a size of 19px. you can specify css attributes (px/pt, border-style, ...) for these input fields and you can even change the text of some other variables on the page -- ever wanted to change the "Who Can Post?" text?
examples:
the new fields added to the "Styles" CP
an example of the POST page with CSS.
it took me a bit of time to do this hack, so it's going to take me quite a bit more time to document it (albeit, it's not difficult, just tedious), so i wanted to gauge if anybody even wants this hack or if there's not enough interest to warrant documenting it.
thanks
