- Patch #18676 by frjo: When anonymuos users are allowed to add comments there are a required e-mail field. This field are, as far as i can see, not shown publicly. A user asked me about this and after confirming that it is not shown publicly I added a description that inform the users of this.  I have included a patch that add the description "The content of this field is kept private and will not be shown publicly". This is the same description that is used by the profile module.
