I didn't see a thread or policy concerning this, so I thought I'd start a thread. My question - is there a policy on the crediting of professional work in our stories? I don't necessarily mean George Lucas or LFL; I know some people put disclaimers in their first posts, but I thought there was a general understanding that as long as it stays low-profile, Lucas won't go after fan fiction. I'm more concerned about other authors. I believe some sites - I think it was ffn - do not allow stories in certain fandoms because the authors of those original works are known to threaten lawsuits. So how should we deal with things when we write crossovers, or if our ideas or inspired from a novel or movie? I admit to using quotes from Lord of the Rings in my story titles, and another story was titled after Shakira's lyrics. I was careful to note this, however, either in the first post or when I used the quotations. Is a simple disclaimer enough? Should TFN be concerned about if, for instance, Disney becomes upset at a Lion King/Star Wars crossover? I once thought about writing an Alias version of a Star Wars story, trying to follow the show as closely as possible. To be honest, I'd essentially be stealing the plotline and throwing it into the GFFA. I doubt JJ Abrams reads our boards, but should I avoid posting stories like that just in case? Does putting in a diclaimer really protect the author then? Should it be required of all stories like the ones I've described, if not for legal protection but out of courtesy to the pro-authors? Or should it be more of an etiquette thing and not something the mods should create a rule for? Or do I just think too much?
