Starting Student Blogging

One of the second grade classes at my school is going to be working with me on their own blogs.  The classroom teacher is very excited about working together and having the students publish their writing online.  I am asking those of you reading this, to please be sure to comment on these wonderful students' blog posts.  I will update this post with the website of the blog as soon as they write their first posts.  Anybody have any good resources for blogging with students?
