Learning Management in the Classroom

I was wondering what, if any learning management systems people used.  Do you use these to communicate with your students? Create lessons? Share files? Grade posting? Group work? Forums?

Response Learning Managment in the Classroom

I was thinking of the Self-Contained Elementary Classroom.  I could guide the students in creating a digital portfolio.  I'm not sure I'm ready to host a moodle.  Perhaps assigning a number and posting grades on page of classroom blog. I guess there are certain things that technology doesn't facilitate.  I mean, we have enough paperwork already!  Any creative ideas on assessing content created online?
