I think stating that someone's work is pointless is being a little harsh. Especially since C2 auditing is at the server level and audits everything on the server to a pre-determined location. The article outlines how to audit specific events in specific databases to a user-defined location. Why would I want record and then have to sift through every action on the server when all I really need to know about is activity in one database?

If you think C2 auditing is a better solution for this specific purpose outlined in the article then take the time to offer something constructive instead of denigrating the work done by others.
