I would like to help the documentation project by editing/adding to http://wiki.centos.org/HowTos/Nagios. Hopefully that means I can have a "development" area I can do my stuff before it becomes approved and goes into production. =) One of the (selfish) reasons is that I recently got nagios running in a centos 6.2 vm and would like to share that experience, including suggestions to make life a bit easier when adding new victims to nagios. I have a feeling a lot of the stuff would apply to earlier versions. Anywhoo, my wiki username is MauricioTavares.
