  * When you notice it "popping into" a page from the spring, please let me know what link you clicked.

* Unix is case-sensitive SO PLEASE CALL YOUR DIRECTORY "CSC152" 
  NOT "csc152"
  * cd /home/username
  * mv csc152 CSC152
* It's up to you what you write down.  However, starting tomorrow, I will assume that you can

  * Set permissions to permit or deny access
  * Change present working directory
  * ...
* Permissions, in general
  chmod [ugoa][+-=][rwx]
