I was what Wendy Kramer calls a "lurker." I would check to see if anyone with my donor number posted, but I did not post because I was concerned about maintaining my privacy. I did respond to a post by a family with the same number, but because I had not posted any info, they were rightfully skeptical, and did not respond. Wendy reassured me about my privacy concerns. I posted my information, and was contacted by two siblings within 24 hours! We have confirmed that we all used the same donor, and all the children have been in communication with one another. I'm grateful to Wendy for this site, and for her encouragement.
