Digital Citizenship Internet Safety

I went into my facebook account.  I know that I have previously made sure that my posts are only seen by my friends. However, after watching the video about making sure to go back and check your settings monthly, I did this again.  The settings are still the same as before but now I will be more aware of checking this often.  I also went through and updated my friends list, making sure to defriend anyone that I do not know.
