I was told when I began looking.. (I asked the people at the adoption agency) I needed to fill out a bunch of paperwork basically saying that if my birth mother wanted contact with me, I would allow it. But they wouldnt be able to contact her. She would have to contact the adoption agency herself, trying to find me. I was also told there was a fee.
There is also a place on here that you can put in all your information, and if she happens to search for you.. there you are
Vice/versa, you might check to see if she is on here already..
I was also contacted by a lady, who offered to help me look. She knew what she was doing, at the time I just didn't take her up on her offer... I don't remember much about that, but there may be other memebers who know something. If I can remember I think they're called search angels or something like it...
I was found on myspace..
I don't know if I was much help to you, but good luck on your search, don't loose heart, it can take time.
