not really, go back in the history of this forum... it's been brought up several times before...
http://www.jimbutcheronline.com/bb/index.php/topic,13033.0.htmlabout copyrighting your materials
http://www.jimbutcheronline.com/bb/index.php/topic,12929.0.htmlabout someone else's copyrights (locations, places, etc)
And that was just two pages back. I had a long boring day off from work a month ago and read almost every post here (which I highly recommend, its tedious but there is a LOT of helpful topics) and it's been brought up several times. Chances are, nobody else felt like dredging up or replying to a topic that has been discussed and discussed and discussed.
Clift notes version... nobody has a firm answer. Some say that as soon as you put it on paper, that it is your intellectual property and no copyrights are needed. However, how do you prove WHEN you wrote it down? Someone suggested priority mailing a sealed copy of the materials to yourself (which seemed like paranoid overkill to me), but others said that this probably wouldn't stand up in court.
Someone had mentioned a copyright website, but I think that really only applies if the manuscript or WIP has been published.
Personally I'm of the opinion that anything I write, stays on my computer for my eyes only. I don't mind posting excerpts of it for workshops, but NEVER EVER EVER EVER produce a full copy of your own work in one place. Even with agents and publishers, they usually only ask for the first 50 pages of a novel - never the whole thing.
hope that helps
