Aren't they legally obligated to tell you to take something down before the copyright becomes involved? Since we aren't making any money off this, I'm not to sure it's covered. The only problem is the fact that GW tend to be more copyright enforcing, but I am still not sure if this would be included.

I recall reading something about the legal aspects of this sort of stuff once, and it said something along the lines of "Unless someone or their company officially states that they do not want any fan work done under their universe, they are required to first issue a warning for any works they wished to be removed."

Off the top of my head, I only recall there being maybe 5 people or so who released these orders, so if you looked into it a bit more, you might find that it is indeed allowed.
