MLA CE Week 2

I thought a Blog would be most useful for a library newsletter or something where I wanted to post content without other people contributing to it. A wiki, on the other hand would be most helpful if I was working on an article with other people. In the past, when I tried this, it was hard for me to keep track of the correct version because my 'Show Changes' button in Word didn't work correctly.
As far as week 2 goes, I couldn't figure out how to and the class blog and wiki to my blog roll. I put a question in the comments for week 2. However, I don't have an answer yet. Do you think you could add a section with additional help for the exercises. It was hard to go through all the questions which were asked when I was trying to find out how to do something. Perhaps it could be a spoiler section or something. I am learning a lot, so cudos to MLA and all the instructors.
