I have a suggestion:
When we are in the Secondary Exoscience Message Board, a list of topics appear. After i have clicked on a topic and finished whatever contribution (if any), i return to the main list of topics. I note this topic i have just finished now is highlighted in gray. If i have already entered into two topics and then return to the board to select another topic, i note that those two previously selected are highlighted in gray, also. May i suggest you change the gray to say, red, so that we may distinguish it better for, you see, the original colour of the script is blue, and gray and blue are not easy to make apart, especially on monitors of lower qualities.
I would personally appreciate such a change to the board.
