Dear ProfJK,
Unfortunately, using your e-mail address as your username is not a good idea. Wikipedia content is extensively copied and the site itself is one of the most visited sites in the world. Any edit you make on Wikipedia will have your username attached to it, and using your email address will make you a tempting target for spammers. We recommend that you change your username at Wikipedia:Changing username in order to prevent abuse.
If you need any help, simply contact me on my talk page, or go to Wikipedia:Help desk. Another option is to place {{helpme}} on your own talk page, and someone will come shortly to help. Remember to sign your posts on talk pages with four tildes (~~~~). Again, welcome!

As you use an email address as your user name that is of the same name as the person about who the article is written where we saw your only contribution up to now, may I ask if you have a conflict of interest? Please be aware that this is supposed to be an encyclopedia and you should not edit articles that you are related to. You may however suggest improvements in the discussion. Please make yourself familiar with wikipedia rules. First of all, read about the guidelines on conflicts of interest. Knopffabrik (talk) 20:35, 27 January 2011 (UTC)
