Okay, I've been lurking here for a while (in my professional capacity as a lexicographer) but finally think I have something of interest to post. (I hope this isn't too spamalicious.)

Oxford Univ. Press has a fairly difficult word quiz up on their site (http://www.oup-usa.org/noad/quiz.html). The password is "kulcha." If your correct entry is chosen, you win $10,000 of Oxford books. (That's ten complete OEDs for those of you who want ten complete OEDs.)

Feel free to email me with questions, but I can't give you any answers. Posting here is all I can do...I want to see a real word person win this.
