Some general site policies that I think should be considered:
Strict, and I mean strict, enforcement of only using public domain images. That means either from Wikimedia commons or images produced by ourselves. No illegal copywrited images from websites.
No, and I mean no, bashing, flaming or trolling. This is a wiki, an encyclopedia, so we stick to Wikipedia's neutral point of view policy.
No advertising at all.
Videos and images must be of high quality.
