MSN China Adoption Forum
There are lots of forums that specialize in the subject of China adoption but my favorite is this one:
It's a private MSN group with more than 600 really nice families who are in various stages of the China adoption process. No cliques, no board wars. Just nice people.
If you apply for membership (it's free), be sure to mention that you got the link from this blog and also mention where you are in the adoption process.
