First: congratulations for the new forums, it look much more consistent and seems to work much better. Even the times are now all displayed in viewers local time - as in the asp.net forums. There is another similarity: it seems to use the same buggy routine for calculating "today" and "yesterday", based only on server date.
If my local time is 8/24/05, 0:30 and the server time 8/23/7:30, "today" means for me 24th, not 23rd. Not a big problem, but sometimes irritating for the user.
