Delete User

Goal is to have all my ROS account consistent accounts across computers consistent with the same user name "eepp". The easiest way to do that appears to create a new account on Sisters for eepp and delete the existing account ed. 

 eepp@sisters:~$ sudo deluser ed
   [sudo] password for eepp: 
   Removing user `ed' ...
   Warning: group `ed' has no more members.
   Done.

 eepp@sisters:~$ ls /home/
   ed  eepp
