Agorism is a new philosophy and has only been around - not to mention neglected - for about thirty years.
Understand that Agorism runs in phases and that the organization of Agorist cells does not come in the first phase.
Right now, you probably view yourself as being in phase 0 - in the Micro terms, as SEK3 would put it. I, personally, feel I'm transitioning into phase 2.
At phase 0, however, nothing more can be done than getting to phase 1, that is, you must put the petty reformists and conservatives behind you and redirect your ideas towards direct action. Once you get here, you'll be in phase 1. In phase 1 you begin to form your own personal allies and you will see a natural organization forming. The organization will form out of other similar, though of course less radical, organizations if you're any good at subterfuge and sabotage. Once you have your allies together, you can begin to talk about trade and developing Agorist projects in your locale.
If you're interested though, I am in the process - the slow process - of developing a website that will serve as a publication for Agorist materials and a network for international Agorists to form bonds over that can be relegated down to their own localities. The project is called, The Counter-Economist, and I'm looking to put the site up soon.
To answer your questionthough, no, there is no "secret word" that you can use, at least not yet. It seems that you're looking at Agorism from a natural hierarchical perspective. You must understand though, there is not, nor should there ever be, an organization that will hand out orders from the top - at least not until the New Libretarian Alliance morphs into a Revolutionary Agorist Cadre/Congress/etc. Agorism intends to spread naturally through decentralized means empowering individuals to move by themselves. Yes, your comrades will help you glaldy, but not if you don't help yourself first.
