Once more, welcome to the My English Wiki Anonymous user! There are very few policies which apply across all of Wikia; the ones that do can be found at their Policy Category. Try to approach the rules, regulations and policies with a little common sense; most of them are self-explanatory so try and adhere to the spirit rather than the lettering of the rules, and be prepared to break the rules on the rare occasion when they conflict with the goal of improving the wiki XD
