On a Different Note... Report Cards

The school I teach in is finally trying to make its way into the 21st century by thinking about going electronic with report cards and comments.  I am on a fact finding mission, trying to see if there is an easy way to have all the teachers input info into a blog like setting that allows the administration to look it over and make their own comments or ask questions.  If anyone out there knows of a way that your school district does this, or if you have an idea of your own that you would like to share, please let me know!  Thanks!
