"Dear Katie..."

Is there a question you're burning to ask Katie? This is your chance.

Send us an e-mail with your question – one question per e-mail, please – and over the next several days we'll sift through them and ask Katie to answer them.

A few ground rules:

Questions must be serious and substantive. (But witty and substantive will also be accepted.) No questions about hair, makeup, shoes or wardrobe. Please. Pretty please.

Questions must be brief and to the point. We may edit them for length, clarity and, yes, grammar.

To keep our e-mail box from being overwhelmed, we're going to ask that you limit yourselves to one e-mail per viewer.

We would appreciate it if you would include your name and hometown . They may be used if your e-mail is chosen and posted.

We'll post your questions -- and Katie's answers -- in a few days.
