There a small bit of bad and/or confusing grammar in the sidebar of the license
chooser results page:
"Mark a document not on the web, add this text to your work."
That is awkward language and should probably be more like:
"Mark a document not on the web by adding this text to your work".
Indeed, I have noticed that the current Spanish and Portuguese translations took
it into their own hands and corrected the grammar in their own translations.
