You need to be owner to get write access, so log in as one of the owners
to write to files of that owner only: cen or col or cre or cs or fap.
The group mail and others don't have write access.

Quoting the command you run e.g. "sudo ls -l /foo/bar/" is useful, it's
also useful to run "sudo ls -ld /foo/bar/" to see permissions of the
parent directory and to run and quote "id".
