This is not a bug because I understand the difference between a thread and the message...

Who else finds it annoying that when you read a message by clicking on the "Last Post" message in the top level "Forum List", then if you go into the Forum itself, the thread you read (the last message of) is NOT marked as Read, even though when you read the last post, you have more likely than not, have already read the entire thread?

Like I said, not a "bug" per se, more of a "nit" to pick
