Shoot! My lack of detail orientedness has gotten me. I skimmed the op (but clearly did not read carefully) and in impatience to vote (just got done reading every single post to a 13 + page thread as well many more pages of contained linked threads and was by this time feeling antsy to actually
participate somewhere) I thought I knew what was going on and so voted for Ej because
clearly that was the proper option for a slightly expressed J type who was the eldest. Um...clearly...yeah.
Then I saw Oj on the list and thought, "hmmm...wonder what that's for?"
So in the end I mis-voted. (if I can correct that somehow, let me know)
I am the Eldest, but not an Exclusive. My vote should have been Oj.
Sorry.
