Arrow things?

what are the blue arrows on the left side of the screen where there a usually the things that tell you if a thread is old/new posted/not posted? i would say that it just means that they are moved except that it says that i can't access one of them and when i look at them on the screen it does not say how many posts are in it? sorry if this is confusing. ok thanks

They mean that there are new posts.

If you click on one, it should bring you to the first unread post of that thread.

Moved to Feedback.

And yeah, it will bring you to the first post in the thread that you haven't seen yet. Nifty little thing. I never use it. =P

...that about answers this question, then.

EDIT: Ah... you were talking about THAT arrow.

Similar to how there is an image for new posts, no new posts, etc... there is also that blue arrow, which means the thread has been moved.
