Mr. Hoggins, we do not do any content filtering. We provide private groups for you & your students that you are responsible to monitor. We do not do any filtering as filtering is too subjective and we feel the teacher monitoring is a better solution. Students can only post to the group as a whole or directly to you. They can not send a private message to another student. Let me know if you have any more questions.

I loved your book. The topic is very unusual and this makes it more attractive. I have been following some of the tasks in this course.
Unfortunately I have not been able to do any of the activities. I am learning at this stage by observing to what other people like you have done.
I am going to ask another group similar to the one we worked with before to join edmodo.
The Mexican students you had met , are now working in their podcats.
By the way, I changed the stting ans I am now receiving new posting alerts in my mail. I feel connected now.
Thanks for sharing.
