Regarding copyright and the internet: On one Facebook thread, people started debating whether I'm right to ask for credit for my own work, and whether content put on the internet is "copywrite" or "copywright." (FYI, it's copyright, people.) People automatically own the copyright to what they create. Filing for copyright with the US government grants additional legal protections. Just because someone posts something online, that doesn't mean that it's "public domain" or that they've given up their copyright. If you share an artist's work online, ask their permission first and/or credit them somewhere with a link back to their website. Most artists are fine with that.
