If you are using Blogger for your class blog, you need to upload your swf Flash movie to a hosting site before you link it to Blogger. I handed out directions on how to do this hosting using Dropbox, but I have been sent alternative approaches using Google. I want to pass this technique along as it may prove easier for you. I have no preference as to the approach you take...I just need to see the end product (your movies and weekly maps posted to your blog). If you find another way to do the hosting, feel free to comment to this post with info.
