Let me know if Wyttenbach takes his quasi trolling too far. He can sometimes back himself into an untenable position which he then defends with insults, but I'm not following the 62Ni subthread closely enough to know whether or not that's the case in this instance.
Well, this is the playground, after all. As far as I'm concerned, I think this is an entirely appropriate place for Wyttenbach's comments, as there is no pretense that 'playing' has to be contributory or productive. My suggestion regarding contributory comments he might have was regarding topical threads, and it appears that he's made substantial contributions at times in topical threads.
But I appreciate the moderation in moving his and other's here from RvD, based on the quality of the content.
