There are very few policies which apply across all Wikia. These can be found on the Central Wikia at Wikia:Category:Policy.
See also Project:Simplified Ruleset
Adding [[Category:Policy]] to any policy pages will add them to the policy category. This is found here.
The above links are the general guides and should be enough for a cooperative community in scoobypedia. Other policies for this Wikia will be decided by the wiki community. It's generally best to keep policies as simple as possible, and not to introduce too many rules. If however we find ourselves needing more guidance, raise the issue in the discussion page.
With due diligence and common sense we can avoid being too active here! Some reminders
Style Policy (aka Manual of Style)
As this is not really a policy, but rather a consensus of opinion that gives the wiki a standard/format to follow; the issue should be discussed in Manual of Style, but it can be added to the policy category.
