Why are netiquette and security important issues for teachers dealing with blogs? How can they be dealt with?
Students should be warned against using offensive language or content and should become familiar with basic netiquette rules. They should be aware about cultural differences. Anonymous posting should be banned. On the other hand they should be aware that anonymity is not absolute on the web and that they may be held responsible for whatever they write.
These are some of the things teachers can do to keep their blogging environment safe:
Set yourself as blog administrator for your students' blogs. This way you can edit or delete offensive content.
Enable comment moderation in the class blog and encourage your students to do the same in their own blogs.
Set up a "comment notification address" to be sent comments by mail as soon as they are posted. (Comments tab)
Set up a BlogSend Address (E-mail tab) to be notified when someone writes a post in your class blog.
There must be other tips more experienced bloggers can suggest.
