Personally, I would like to see the NagiosCommunity wiki become more
populated.
I would assume it would be moderated by at least Ethan which would assist
keeping high integrety.
and he has been keeping the Blog updated with some interesting articals and
events.
I am hoping to find some time in the next few weeks to put together some
overview documentation on NC_net and Windows monitoring to contribute. I
think it would be nice if any SNMP experts could contribute something to
help SNMP beginers get there feet wet.
