Edmodo

I was recently introduce to Edmondo at a Laying The Foundation Traning. My instructor gave us some great tips on how to use it. Most of the teachers in my session had never heard of edmondo. My instuctor taught high schoolers and I feel that some of my middle school students may no use it to benefit them if you know what I mean. I noticed it was mentioned in our class reading assignment. I really want to use this tool in my class this year. However, I still have lots of questions. I am worried about students who do not have Internet access at home. It will not be beneficial for them. Not to mention if a student post something inappropriate. I plan on giving parents access but worry about students who post things inappropriate before I can get them removed. Have any of you used this tool? If so, please let me know how well it worked for you and if any problems occurred.
