Hi. I'm Robin Smith. I don't actually exist, but I can show you how to create a wiki page. Click on the edit button to the right to see the source for this page.
You can add links to topics you want to discuss. For example, I like Indian Cooking. You may want to prefix the page name with the word Main, as in this example, otherwise the page will be put into the Profiles category (which is where you are now). You can even link to pages that other people have created. For example, link to your friends, or to pages that describe your favorite hobby.
If you want to add a link to an external webpage you can do this, like http://web.engr.oregonstate.edu/~budd.
You can add a picture the same way, as in http://web.engr.oregonstate.edu/~budd/images/smalltimNphyl.jpg. Alternatively, if you have a small photo, you can just put the URL in line, like 
A small photo will be helpful to the instructor, and other students, making a name/face association.
