Pete,
The elevation of a campaign to "Operation" status is a determination done when the campaign is submitted (or planned even). The guidelines stipulate the following:
Operations
There are two distinct types of Campaigns. The first are Operations. They are generally larger in scope than a normal group build. They will also have a high-level of educational value to the build process. If you want to dig out the books and do research than this campaign should interest you.
Missions
The second type of campaign is the Mission. Missions can have as many participants as an Operation, but will generally be more about building models and less about things like historical battles or learning to create a water effect for a diorama. Missions will be the far more predominent form of Campaign on Armorama.
I noted that "By the Book" is now listed as an Operation. I will check to make sure it is placed in that category appropriately.
Thanks,
Jim
