Has anyone ever tried online counseling for postpartum depression?

I've heard of more and more people trying online therapy, but I've never tried it myself. I came upon a site called Tranquil Counseling that specializes in postpartum depression counseling. And it's done online through e-mail and live one-on-one chats. That would be amazingly convenient for new moms. Imagine laying your baby down for a nap and then going into the next room for a PPD therapy session.

Tranquil Counseling is apparently located in Indianapolis, Indiana, but helps people from all over the country. I checked out the fee and it looks really reasonable compared to off-line rates; $95 for a 60-minute chat session and about half that for an e-mail exchange.

I'd be interested to hear of anyone else's experience with online counseling.
