Don’t edit the Twenty Ten theme. Your changes will be over-written the next time you upgrade WordPress. For this reason, it is recommended that you consider creating a child theme for your customisations. Once your child theme is active, we should be able to help with the customisation.

ok, would it work if I copy the twenty ten stely.css theme? I DON’T know how to create themes. It shouldn’t be this difficult… I need ot have the fade in opt in form and I have too much stuff on my blog to change the these. Other themes do fine with this fade in opt in form… Please let me know.
