Textarea CSS for a E-newsletter Widget

Hello,

I am looking to make the newsletter subscription form at the bottom of my page have the same style as the textarea for the login that is at the top. I have tried copying the style for the Login-form over to the style for the newsletter widget but I am not having any success. The stock newsletter that came on this them was not functioning so I went with your e-newsletter plugin. Any help I can obtain would be much appreciated.

Thank you!

John
