After a few months, I am finally able to access the 'Diocesan Information Systems Conference' discussions online (it uses some sort of Lotus Notes system), and it's actually a pretty good resources for IT administrators. There are a lot of great discussions about social networking, network stacks, and information management.

If you work in an (Arch)Diocese, you should head over to the DISC site and request access.
