Personal use means you can make your own copy to pencil in changes for your campaign or cut up to give your players a room at a time. Putting it on the web is publishing and about as far from private use as you can get. Not that I expect WOTC/Hasbro will really care, but unless it has been specifically released for general use, this is a copyright violation. (Disclaimer: The previous is my own best understanding of copyright law. I am, however, not a lawyer, and this is not intended as legal advice. Should you need legal advice concerning a matter of intellectual property rights, consult a lawyer specializing in intellectual property law.)

Wow, I didn't realize D&D was that old. :-)
