What's with the + signs in front of threads?

It looks as though each thread is in need of medical attention.

I don't see any, maybe you got a virus and are in need of medicine.

well I can see them..
they do look silly though.

They must be bored deactivating links, so its time to re-design the antiquated platform:)

If you have Firefox talk to Admin. I can't see a plus sign, but I do know there is a problem as I have spoken to admin about the problems I've been having. You have + signs, I have pink letters lol

Doesn't it mean a new (unread by a given user) comment has been added to a thread?

It looked like all the threads were now Bishops...

It appears so - but I have never seen this before.
