It would probably be useful if an elder (current or former) would post what kind of information the local Body of Elders keeps on each individual publisher.
I know that there is a publisher card for each individual that contains some basic personal information. I also think that there is some kind of record kept regarding judicial proceedings, but I'm not sure of the details. I also don't know what kind of information is sent to the branch, though I don't think that it's extensive.
