Hi Stephen, Thanks for your post. In order to add a person like your father to your profile, you would need to become a full member.
In addtiton to clicking on Volunteer button you would need to finish the process of filling out your tags as now required. Once you do that you will be confirmed by one of our friendly greeters!!
Here's how to do the Tags:
You may want to add some tags on your page indicating a family name for one tag and a specific location like a country, state etc you are interested in, for another tag and then add other surnames or locations as tags as desired. That way you will be connected to others with the same interest.
Click on http://www.wikitree.com/wiki/Special:Following to add or remove tags. Be sure to add comments explaining why you're following the tags. Those appear on your profile too.
