Post!

If someone posted my work on the internet, I would have many differing reactions, depending on the situation. It wouldn’t matter to me what was posted, whether it was a song or a picture. If they had my permission to post it, with or with-out crediting the work to me, I wouldn't care. However, if someone had posted my work without my permission, I would ask them to take it down or at least put the work under my name. If the work was something they were making money off of, I would ask for a cut.
