Blogging in School

Blogging is new to me but I think this will be a great adventure for me.  I did a search on education blogging sites and one that I came across was www.schoolrack.com.  On this site teachers, students and parents can sign up.  They offer a smaller package for teachers for free.  Teacherlingo.com is another great site.  It has a teacher resource section along with a blog and message section.
