I did understand something at least :)

Yes; I'm in the tech group:
andy.graybeal at buddleia:~$ groups andy.graybeal
andy.graybeal : andy.graybeal adm dialout fax cdrom floppy tape dip 
video plugdev users fuse tech

And Nancie is in the finance group:
andy.graybeal at buddleia:~$ groups nancie.buerkel
nancie.buerkel : nancie.buerkel adm dialout fax cdrom floppy tape dip 
video plugdev users fuse finance
andy.graybeal at buddleia:~$

Here are the ACL's on the tech folder:
andy.graybeal at buddleia:/srv/Desktop$ getfacl Tech/
# file: Tech/
# owner: root
# group: tech
# flags: -s-
user::rwx
group::rwx
other::r-x
default:user::rwx
default:group::rwx
default:mask::rwx
default:other::r-x

andy.graybeal at buddleia:/srv/Desktop$

And here are the ACL's on the finance folder:
andy.graybeal at buddleia:/srv/Desktop$ getfacl Finance/
# file: Finance/
# owner: root
# group: finance
# flags: -s-
user::rwx
group::rwx
other::r-x
default:user::rwx
default:group::rwx
default:mask::rwx
default:other::r-x

Let me know if you figure anything out.  I'm still wondering if I should 
be approaching this differently.
