Just found out that I have a half-sister out there somewhere........

Thanks so much for your support! My mom didn't want to pursue her, as she didn't feel like she had the right to break up her life, as she knew it and she was also afraid that her aparents may have not told her that she was adopted. Mom has sent all of her medical records to her. Mom also let the agency know that she would be glad to meet her, if she wanted to, and that she didn't care what the bfather said. We'll see. We are keeping an open mind and that "shock" (for me) is wearing off some. I think that this site is great! Did your aparents ever tell you why they didn't tell you that you were adopted?
