A couple minor quibbles:
1) It appears that every thread going back to around mid-January is listed as unread. Just a bit of an annoyance looking for the newest threads and the last unread posts, which shouldn't be a problem in the future but could bother people as they log in for the first time.
2) I can't seem to find some of the same board options as before, particularly the ability to change the number of posts per page. I always like to set that to as high a number as I can so I'm not constantly clicking through new pages, but I'll get used to fewer if needed.
Other than those, this looks pretty good so far. Nice work.
