The Cross-Wiki Weekend is an annual event celebrating the anniversary of Nintendo's founding, hosted by the Nintendo Independent Wiki Alliance (NIWA). The purpose of the event is to invite users to edit other wikis they rarely or never edit. After the event ends, users who participated are encouraged to enter into a drawing where one lucky winner will get a Nintendo eShop gift card! The 2021 Cross-Wiki Weekend will take place from September 24th to September 27th. You can find more information on the NIWA website.
Want to help the MarioWiki?
If you come from another wiki and are looking for ways to help the MarioWiki, we suggest you to take a look at our maintenance page, which lists a variety of tasks for users to help with. Some categories require more knowledge of the Mario franchise, like wanted pages or stubs, but there are many others anyone can help with! Our monthly newsletter, The 'Shroom has a project called Spotlight which features items from several categories that need to be worked on; if you can't decide where to start, this could be a great place to do so. If you need help, feel free to read our Manual of Style or to contact an administrator.
Want to help other wikis?
If you are a regular user of the Super Mario Wiki and want to help other NIWA wikis, check out the editing guide, which has links to all wikis' relevant maintenance pages.
