Well my good sir a skid I undoubtedly say that most individuals on this site will most likely copy and rewrite other individuals code. But, not every person on this site will. Due to California law statute code 201 sub section A the copyright law says "Copyright in a work protected under this title vests initially in the author or authors of the work. The authors of a joint work are coowners of copyright in the work." There must be an agreement for said copy and rewrite. With this said most people do not realize the consequences of copy and calling it there own. I say good day sir and good luck to you.
