Thanks for letting me observe how to use this social
network.. I'm getting the hang of it. However, I want to know,
what our role as observers should be. I know a lot of students
have greeted me and I have replied to some but I don't want to
go any further unless I have your approval. So now I have
another question. If I created my own social network I can also
be a member of other social networks right? Can't the students
do that as well or do we control that as well?
