How to pick a good Adoption Agency?

Hello Ladies,

I have been a member less than a week, but the amount info I have assimilated is amazing! Wonder how I missed this site all these years!!
Have few questions to all those who went through the adoption process,

1. What are the things to watch out for and how to pick the right agency?
2. How can we hasten the process?
3. Is it possible to get the adopted child's family background details for medical records?
