The other day, I noticed that MacPGP seemed to give credit to a person with the initials L. D.

He certainly seems unpopular...was he at one time a more positive force? Or is this a dumb question on my part?

Yeah, it's him. A couple years ago he was a nice guy. For some reason he got upset with a few people on cypherpunks (to this day I don't know why), and ever since then he has been posting and sending them flames, mailbombs, and harassing them in other ways. Detweiler is a smart guy with some sort of strange psycological problems. Maybe he is on drugs or something. I don't know. The things he does just don't make any sense.
