I think current situation is fine more or less. There is quite many active campaign managers and every has his own methods how to manage campaign. And most are doing their job well. I think it's more users problem that they are lazy to check what rank campaign is looking for before applying. If they can't do even such small tasks, I don't think they can be eligible for campaign.
Though, I agree with @Lucius, abbrevation CFNP may look confusing because it's not widely used outside forum and it have multiple meanings. I remember that I also had to look for explanation in Overview of Signature campaigns to find what it means. But now I don't know good alternative to replace it.
