So, today another outside wiki, for the Serpents Hand, was brought up in 19. They didn't have the CC attribution, so Echo posted on their website about the issue. There was also the Chaos Insurgency wiki, which I believe was posted about here before but I could not find the thread, which we could not find the CC licencing on. Both of these wikis are made by JaredFleming. I have made a Wikia account, and I'll be keeping watch on him to see what he does in the future.

Apparently there's also a WikiDot CI site related to the Wikia one: http://cii-wiki.wikidot.com/
I'm sending them a modified version of the thing echo posted, since it seems to cover all the bases and I didn't feel like writing my own and hopefully he will be in full CC compliance soon.
Whether you like it or not, history is on our side. We will bury you!
