I love earthymommies.com (I think that's right).
Fill out the application, I used to talk to them a lot but lost my wifi and now that I have it back I need to reapply (been over a year since I've posted on the site) - just never have the time.
Be serious, it's not for lurkers or others who want to play around.
They are a fabulous wealth of information on natural child birth and take their site seriously.
best of luck
