There are very few policies which apply across all Wikia. These can be found on the Central Wikia at their Policy Category.
In addition to those policies, there are policies and guidelines that have been developed on the Plunderer Wiki to further our goal of creating an informative Plunderer database.
Policies apply to all editors. The Plunderer Wikia strives to create a welcoming and fun environment for those who are civil to and assume good faith in others, seek consensus in discussions, and work towards the goal of creating an increasingly comprehensive database about everything in the universe of Diamond no Ace.
Other policies for this Wikia should be decided by the wiki community. It's generally best to keep policies as simple as possible, and not to introduce too many rules. A growing wiki can usually do well with a few simple policies and a lot of goodwill and cooperation.
