• Inconsistency. Some messages say a page is "protected" and some others say "locked".
• Incorrect expression. Not all "registered" users are autoconfirmed (in the semi one).

 Done I've fixed the first issue in all core messages I found it in in mwr:70325. Also fixed another inconsistency I spotted. If there is another matter you want to address, please do so in a separate topic. Thanks.
