[SOLVED] RSS email signup box: how to remove it

I followed Juggledad's method to get rid of the RSS icons in the BFA Subscribe widget. Actually, I want to keep the RSS orange logo and get rid of anything else, including the email subscription field. We already have a weekly newsletter, so I just want to allow people to add the feed to their Google homepage.
I added the following to the CSS inserts. What do I have to add to get rid of the email field?
