I agree with those keeping separate boards and with Hank saying we should but the symbol name at the begining of the first line.
I don't always have time to read all three boards so i go to the one that is a priority at that time. This ia a big bonus to me of having them separate.
On the other hand if the board administrators have a harder time dealing with three boards instead of one board, I would say they should be allowed to save themselves the work and consolidate.
