Blog annoucement

Due to some technical difficulties making it hard for everyone in our class to post on the blog, I've decided switch the blog from 'contributors only' to 'public'. Only contributors will be able to post on the blog, but it will be viewable (and comment-able) to the internet at large. These changes won't go into effect until monday, so if you want to change your screen name for more privacy (so this blog won't come up if your name is googled) you may do so. Please let me know if you have any questions or concerns.
