“ The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. ”

A good place to help is at Category:Works with no header template. Each of those pages is missing a header, which means that the author isnt clearly defined, and it could mean the page is a copyright violation. ”
