I logged in a few minutes ago and saw Chat (3) in the bottom ribbon so I went to my shoutbox and saw three lines that were posted seconds after I closed it the last time I was in my ShoutBox. Now that I've been to my ShoutBox, shouldn't it now say Chat (0)? I even logged out and back in snd it is still at (3).

Never mind. I see that all I had to do was post a comment of my own.

yes.
you have to post there to mark your ShoutBox as read.

There should be a little green question mark next to the link that indicates what the number in parentheses means. Sorry for the confusion.

No apologies necessary. The green question mark is just barely visible on my screen. I would never have seen it if you hadn't pointed it out.
