मोड्युल:Requested move
मोड्युल कागजात[हेर्नुहोस्] [सम्पादन गर्नुहोस्] [इतिहास] [ताजा गर्नुहोस्]
This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |

-- new1 parameter, so that the syntax for the old templates
