Here's 2 New features that are not so obvious:

We now have a PM (Private Message) feature, which is a way to communicate with members without sending emails. Members can include up to 5 recipients and keep track of each (as to who has read what).

Regarding the 'Online' indicators, the little guy included in that is a 'mood' indicator. (Try hovering over it to see what it says) He is also found in the top right-hand corner above the FAQ link and can be changed by clicking on him.
