The Cross-Wiki Week is an event in which the wikis of NIWA encourage their members to edit wikis that they have rarely or have never edited before, in an attempt to get some fresh ideas. Those who participate can then enter to win a $20 Nintendo eShop gift card by claiming their edit once the event starts. They should include the name they used (they must use a username, and may not enter an IP address) and the wiki they edited, and their edit summary should include #cww. There will be two winners during this event. One can find further rules and other information here.
