I had played around with Edmodo lots, but had never really gotten the gist of it until I changed my delivery of my homework. You know when you get that "aha"moment..... it came when I realized I could use Edmodo with very little effort on both my part and my students part in terms of management.
Edmodo is the one thing my students consistently go to more than any other site. I highly encourage you to investigate Edmodo and all it has to offer. This is just the tip of the iceberg as there are alot of fabulous things this site can do to help manage your classroom better. Give it a try and see if it doesn't make your classroom management load just a bit lighter.
