i've read alot of people on this site talk about the poor man's copyright and how if you send yourself a copy of your *whatever*, it serves as a form of proof that you created a certain thing on a certain date.
just today, nov 8, 2005, i read this story online about how some guy did that with song lyrics but after going to court with his "evidence" he still didn't have a true copyright for it and someone else owned his work!
i don't know anything about laws but just beware that this is a real life example and that in the end, a legitimate copyright seems to be necessary if you want to fight someone in a legitimate way!
here's the link if you want to read the article (it's a pretty short article):http://music.msn.com/music/article.aspx?news=206610>1=7418
p.s. has anyone actually gone to court over this type of situation? i'd like to hear real life stories rather than hear-say
(no offense meant to someone's sister's friend's cousin who know's someone who that happened to!!!!
