I have installed a fun little application that lets us know how much time people are wasting on BCA.
You can see the Total time, and Avg time people are dedicated to BCA on our leaderboard here:
Time Spent Online Leader Board
(you can also get to this by going to the navigation bar and clicking on Community > Time Spent Online Leader Board )
Also you will be able to see it when they make posts on the right side (where there itrader rating and user count is)
Happy time Wasting!
