[Wikipedia-l] Trademarks and user names

[Jens Frank]

Hello,

A new user registered a few days ago using the name "Harry Potter".
Warner Bros and JK Rowling have a trademark registered for this
name.

On the new users talk page ( http://www.wikipedia.org/wiki/User_talk%3AHarry_Potter ),
MammaBaer posted some concerns about the user name and its legal
status. I'm not experienced in trademark law, so I post this to
the list.

Is the use of a trademarked name as a username problematic?

	Best regards,
