If you're interested, please paste the following into the body of an e-mail (NO ATTACHMENTS), and send it to danengber@yahoo.comby March 31, 2008:

• Your résumé.
• A list of 10 possible Explainer questions, culled from this week's headlines (with links to the relevant news stories).
• If you want, you can send links for up to three clips of your published work.

Those selected for a tryout will be contacted by e-mail no later than April 4, 2008.
