"Go to first new post" has never worked correctly
There are actually two separate but similar issues I'd like to mention:
1. When going to a forum while logged in, threads with unread posts are supposed to be highlighted in bold text. This is hit-or-miss on bikeforums -- sometimes there will be a few highlighted threads but many threads with new posts that are incorrectly not highlighted, sometimes none will be highlighted but should be, and sometimes the highlight feature works as intended. I go to some other vBulletin forums where this feature works properly so it seems to be an issue with bikeforums' setup.
2. "Go to first new post" likewise doesn't always work as intended -- sometimes it will go to a seemingly random post *after* the first new post. Other times it actually goes to the first new post.
Both of these bugs have been present for as long as I've been a member here.
