SDG Wiki:Protection policy
The SDG Wiki is built around the principle that anyone can edit it, and it therefore aims to have as many of its pages as possible open for public editing so that anyone can add material and correct errors. However, in some particular circumstances, because of a specifically identified likelihood of damage resulting if editing is left open, some individual pages may need to be subject to technical restrictions (often only temporary but sometimes indefinitely) on who is permitted to modify them. The placing of such restrictions on pages is called protection.
Protection can only be applied to or removed from pages by the SDG Wiki's administrators, although any user may request protection. Protection can be indefinite or expire after a specified time period.
The following templates may be added at the very top of a page to indicate that it is protected:
