If I choose "multi line" option for the input message field, the text color is barely distinguishable from the back ground.

I am using "Nightfall" template:

I did change the background color to make the form match the template:

.cform fieldset    {
    margin-top:10px;
    padding:5px 0 15px 0;
    border:1px solid #adadad;
    border-left-color:#ececec;
    border-top-color:#ececec;
    background:#2d2d2d; }
