I'm not sure how to explain this properly but...... How do I make my form boxes into underlines instead of actual boxes? So it would look something like this:

<u>name<u/>________
<u>e-mail<u/>________
<u>url<u/>________
<u>comment<u/>________


Thanks :)

Eeekk, I guess html isn't allowed?

Try adding this to the <input> tag:
style="border: none; border-bottom: 1px solid #000000;"
