Just wondering if this theme http://wordpress.org/extend/themes/reference is a copy of Twenty Ten theme? I've looked through alot of the files in the theme and they seem to be the same but with twentyten replaced with the word reference. I've even replaced some with ones from twenty ten, renaming the TT references and they worked.
In my opinion, other than a couple new widget areas and header options removed (which is easily done as a child theme) it's Twenty Ten copied and released under a different name. Am I wrong in thinking this?
