@Rafael, thank you for the personalized help.  Very much appreciated! Looking forward to Forms 2.0.  the other code you gave me worked too!

So, I think I'm trying to do the same thing as Michelle, but I can not get the JQuery to work. I'm trying to do a simple Newsletter signup so it would look something like:

First Name
Email Address

(Custom Rich Text)
Newsletter: Checkbox

(Custom Rich Text)
Blog Emails: Checkbox

I saw where I could add extra line height in the form editor, but it applies it across all areas of the form, where really I just want the extra space above the check boxes.  Additionally, the newsletter opt-in is brought in as custom field. I tried adding:
<script> $jQ($jQ('#C_Newsletter').parents("li:first")).css( "height", "50px" );</script> and saw no change.

Any ideas?  Thanks so much!
