Template:Duplicate/doc
This is the blank template to be copied to the duplicated pages.
{{Duplicate| }}
Paste the page name of the duplicate page in the space behind the pipe and insert this template in the 2nd duplicate (page name "duplicate-2"), like this example:
{{Duplicate| duplicate-1 }} --> template prepended to page name "duplicate-2"
After that, insert the template in to the 1st duplicate page but change the page name to "duplicate-2"
{{Duplicate| duplicate-2 }} --> template prepended to page name "duplicate-1"
This template adds the [[Category:Duplicates]] to both duplicated pages. Editors can just check for dupes under this category and retain the corresponding pages accordingly. Pages to be deleted should be tagged with Template:ToBeDeleted for wiki admin to delete as editors do not have the user right to delete pages.
