The advantage of reverse order is that the most recent messages, usually the ones you're interested in, are at the top, sort of like geological layers. The disadvantage for some is message vertigo.
The advantage of forward order is that it's the same order as message display, but the disadvantage is that the most recent messages will be at the bottom. That could be some number of scroll clicks away for long threads.
Whatever the order, the feature is intended to make it easy to find posts buried somewhere in a thread, and to make it easy to see if you've answered replies, and in turn to see if your own messages have been answered. I'd appreciate hearing about any ideas for making navigating through message threads even easier.
I will change the order if there is sufficient demand, which I'll evaluate by posts to this thread. Please post your opinion either way, I can't assess silence.
