Yes, it's quite the mystery! Like a Sherlock Holmes story. :)
I assumed AM found the 2003 post via google and (not noticing the 2003 date) simply banged out a reflex AM reply ... then decided to create a proper PM account and used that to reply three minutes later (still not taking the time to notice how old the post was). jdporter could probably tell us if AM and KABA are one and the same ... or (better), if KABA is still listening, he/she could tell us the back story.
I won't be able to sleep tonight not knowing. :)
