Regarding my problem of "missing" user directories following an upgrade from 10.1.5 to 10.2 - I have discovered that the previous student directories and their work are located in the invisible Volumes directory of the server. I'm not sure what specifically caused this (does journaling save info here?) but I'm sure this is not proper behaviour. In any case, I am going to try copy some files from a previously created test account back into its appropriate /Users/short name directory and modify the path. My apologies for the previously long posting and thank you for your patience. Patrick
