Re: How about a slight wrinkle in this plan?
I agree that timestamps would be good. I used to use them for replies to ACs, until they took them away.
I know we've got an anonymous cowherd (or is he anomolous?) - but I'm pretty sure we're bereft of aardvarks.
Of course, my preferred solution would be proper threading. Everything else is just papering over the cracks for the lack of that obvious answer.
