Hi, it looks like I have found some more bugs (sorry!).
It looks like the notification for unread threads don't work in these subforums:
- Archived Development & Programming
- Archived Libraries & Helpers
- Archived General Discussion
- NetBeans Plugin
It looks like it got something to do with locked threads, as all threads in those subforum are locked.
Also the global "Mark this forum read" have disappeared (or moved?)
