Shawn; thanks for your interest in GenealoWiki for the Dafoe surname. I am on the road right now, but I do check email and the website. So to get started, go to the website and get registered. Once set up, I will send you startup instructions. So visit: www.genealowiki.com
and click on the Register link that is near the top of the left-hand column. Enter in your information for us. This is not so much for security as it is to let the other researchers know about you, your interest, and when you make family additions. Once registered, a good spot to head to is the TWiki link on the left (not the Tutorial, we are still planning to work on that). Just follow the examples for details.
Let me know which ancestor in the site is closest to your line and I'll set you up for adding those relatives.
