Reverse chronological in clumps of 75, eh?
I noticed the red links too. Maybe "most active" threads of past few hours or something, who knows?
If I were William (who is doing a great job) I would forewarn on his Forthcoming Changes thread that some of these specific things would be happening
on a given day, then go and do them. The extra couple of minutes to give people a prior alert would help, for a Forum full of paranoids and geeks who
can fly off the handle and get up in arms at the first sign of "change".
