Mike already answered by offering to help. He's like that. :-)
I'll answer as if you're asking "How do I add more to my tree?" and "How do I make my father's profile public?"
To the latter, easier question about privacy: Click the Privacy tab on his profile. You can select the privacy level from there. If he's living he can' t be entirely public but you can set him as "Private with a Public Biography and Family Tree."
The question about adding more to your tree is probably too general to answer well. If you haven't already, see http://www.wikitree.com/wiki/How_to_use_WikiTree
If you have more specific questions, you could post them here on G2G.
