Thankyou! My googling didn't turn anything up and I've reread all of MoR itself in the last couple of days (except the bits I didn't like) so I was failry sure it wasn't in the story itself.

I notice that I myself replied to Eliezer in that thread. Over the last five years or so I seem to have lost the ability I once had to remember nearly perfectly every conversation I participated in. Shame. :)
