the new/unread status of a bunch of thread (this one included) doesn't seem to work for me : specifically this thread wasn't "bold" or didn't have a "jump to last unread" even though it did have new messages (I do have some other thread with new status and I didn't click "mark all read" ever)

any answer on the youtube embeds ?
(if you do add some code there, can you have options to make the embeds widescreen and/or hd)
