Basically, according to Wikia's policies, and creative commons licensing, any time a person wishes to copy information from Wikia, they must say where they got the information from and vice versa.

Here are a few links which directly refer to the copyright I am discussing.

This one  is the simplified version of the law from Creative Commons. The most important part is "You must provide appropriate credit", which means you must provide a link when you use our stuff, and we must provide a link when we use your stuff.

Thanks for making me find it, as I should have linked to it in the blog. :)
