RE: "New post" sign?
Realizing you were talking about the NEW POST on the left of the screen I completely forgot to tell you guys that this is currently available, just slightly different.
Look to the right of a message and you'll see a round icon next to (post no. _ ). Either it will be yellow (new post) or it will white (read post). It may take a little getting used to and I'm sure can be changed later, but cosmetic changes will be in the upcoming weeks as time allows.
