So, I think I have it set up now so that if you post a comment in the website, it will automatically post to Edmodo.  Edmodo only checks for updates once an hour, so it may take awhile to show up, but I think will work.
To me this seems a lot like the wikis, but we can watch the clip and discuss advantages and disadvantages of the two options for us.
This video explains wikis and we'll look at it in class on Wednesday and discuss how it can be useful for us at school.
