Synnen,
Thank you for the suggestion. But if a question comes to me that I wish to answer, I will if it is still open. If the answers feel as if it needs more meat than I will answer it if I am able. There maybe someone else who feels the same. And having different opinions helps the seeker. It may balance the reader as well. Many people flip flop on their desires to find their family members in life. For whatever the reason. It maybe guilt. It maybe anger. Or it maybe that they just aren't ready. This individual may seek her/his answer one day while online. And I feel it is very important for someone to go out of their way, to try to help. Unless, they close a question that is.
Deedy,
There is also a birthfather.com site. You can do a browser search. They are birthfathers who are searching for their children. Some have been reunited, some not.
I believe birthfather.com has a multitude of individuals who are searching. Some through adoption, some through lost contact with their children through the years.
If you know his name, you can try:

You can start with a letter to him seeking information. Such as:
http://members.tripod.com/rombergers/birthfather.html
In many ways, you are just like an adoptee. You are seeking your biological link. Your father.
For adoptees who search, that is what they usually wish as well. If you decide to search for anyone in your family, it is better to embrace searchers and find what works in order to receive a positive outcome.
