Profile pages always take this form: http://www.wikitree.com/wiki/Baggett-154
You could replace "Baggett-154" with any other WikiTree ID.
As Terry says, you could also try a search if you just know the name. http://www.wikitree.com/wiki/Special:SearchPerson
If the person's tree is public, you can click on the tree tab on their profile.
If the person's tree is private, you will need to request Trusted List access to see it.
