- The permissions on the .php file need to be set correctly, or you will
  get a blank/white screen when you run it.
  
- the permissions are: 
        - 755

- make sure you switch your user group to giss
        > newgrp giss

- New this year:
        - There is now a functionality to write namd/title to a file for storage (TalkInfo.talks)
        - However, using the old sync method will erase this file...
        - Now there are 2 sync files:
        1) original: sync-giss.sh
                > sudo sync-giss.sh
                - this will do a full sync, completely matching what is in the local directory
        2) new: sync-giss-excludetalk.sh
                > sudo sync-giss-excludetalk.sh
                - this will sync everything BUT files that end in "*.talks"
