"Reunite" catagory at top of page

I am helping my brother in his search for his biological family. I put his information both here in the forums and the Reunite section above. I was going to it and it asked for my password. I cannot imagine giving them a different user name than I use here, I thought it was all one and the same. But when I put in carolynppk it says it does not recognize the user name. I went to have it sent to my e-mail address and realized that where I live, insight was taken over by comcast. I figured that when I updated my e-mail address here, it updated it for all of adoption.com. I there any way to get this information. I don't want them to think I am trying to be two different people or that there are two different people with the same birth information either. Any help for me? Thanks! Carolyn K
