So I installed the free RealPlayer, after going through the install to make sure it doesn’t add desktop icons, shotcuts, or change my default application with different media formats, it asked be to register the product, so I tried some bogus email addies, and they were all already used:

• asdf@asdf.com
• asdf@asdffdsa.com
• asdffdsa@asdffdas.com
• asdffdsa@asdf.com
