Sister Mary, I am absolutely positive they have your name somewhere on a list.
Nathan, let me clarify. I don't know if you ever took count at a Memorial for example, but every year, anyone who partakes is observed. Any baptized JW who partakes (obviously visitors who partake are not counted) is sent in as a partaker. Thats it.
If they are newly partaking, two elders will talk to the publisher. If the publisher professes to be of the annointed, then it is duly noted on their publisher record cards.
When the CO reviews all the cards, he will see this, and note the name.
Usually, the CO will discuss the behavior of the publisher with the elders if they are newly partaking. If it is a brother, the recent articles about how those who profess to be of the annointed are not to be treated any differently then other sheep publishers will be reviewed, and a likely shepherding call will be scheduled.
If a long time publisher (esp a brother) professes to be of the annointed, then special attention is paid to them. How do you think Morris and Jackson for example got noticed? Yes, they were in special full time service. But that is the point. There is a list, certain names are taken, and they are considered "genuine annointed." Circuit Overseers are depended upon to notice. If a CO believes that a (newly) professed annointed one might not be "up to JW annointed snuff" (my phraseology), then it is merely noted that they partook and are claiming to be annointed.
To me, it is all the more damning that they keep track, because they know better then anyone how much of a sham, both doctrinally and from a simple math equation (less then 144,000 faithful Christians from Jesus time to the 20th century?? REALLY?) their bullshit teaching is.
