The Succession Box and Succession Box 2 templates have been deprecated and the new 'Succession' Template is supposed to be used, but 'we' have to remember what it was changed to, since there is nothing on the Project page or on the deprecated Template pages.
Both Deprecated Template pages have a nice orange banner stating that they are deprecated and to contact Template project for information. Why don't those pages both state that 'Succession Template' has replaced them? There is a statement in other Deprecated Template pages to indicate what the replacement is, if there is one. See the Date Guess page which states that Estimated Date should be used. I would also request that the 'link' should be included for the new template page, as is stated further down on the Date Guess page.
Also, could the Help page for Succession be identified differently than the Template Information page in the Category for Navigation Profile Boxes.
It looks like the page that ends with /docs is for the information page and the other one is for the Help page. 'Easily Confused' has the same page listed twice for the Information page
