A little information about copyright for you: The U.S. Copyright office considers anything that has been set upon a "tangible medium" copyrighted. This means that the second you put it down on paper, it's copyrighted. Now this does NOT meant that the copyright is REGISTERED.
I don't know about other places, but I know on homerecording.com that things work basically on an "honor system." Everyone here has a basic understand of copyright and also have an understanding of what kind of work it is to compose and record a song. For that reason, we don't steal from each other here.
Now if you're worried about people stealing your stuff, there are several routes that you can go.
1. DO IT FOR REAL. Get the forms and save up the money and register your songs at the U.S. Copyright Office. It's about $30 per song or about $30 for a collection of songs under one title. This is the only real foolproof way of doing it.
2. POOR MAN'S COPYRIGHT. You can send a copy of your songs to YOURSELF registered mail. What this does is prove that you were in possesion of the material on a certain date, so if any disputes come up after that date, you have a copy that has been sealed by the US Postal Service. A note here . . . DON'T OPEN THE PACKAGE THAT YOU SEND TO YOURSELF. It would defeat the purpose.
3. TECHIE COMPUTER NERD COPYRIGHT.

This would hold up in court in a pinch, but I wouldn't bank on it if I could do one of the other two options. Since you're posting on this website, I'll assume that you have a computer. Whenever you create a file on your computer, your system stamps it with a CREATION DATE. This can never be changed. Any time you open the file to make modifications, the modification date changes, but the CREATION DATE never changes. If you back up your files to zip disk, you could bring the disk in to a court hearing and show the judge the creation date of that file and it would precede the other person's claim to the work.
Hope I've given you some ok tips.
