I've always thought the design of the board was at fault and stand by it. Its so far removed from the basic design of message boards that people on average cannot follow it. It is helpful to have a separate help board, but then if you click to go to the Message Board there is not a choice to be made for which board you wish to visit. You are dumped on the General one and it as assumed that a user will see the others across the top, which do not stand out one bit from surrounding text. Being in an enclosed table does not make them stand out, it makes them seem separate.
Those who come here a lot can find the other boards, its the new users who cannot because of poor design.
So I guess this discussion is all moot though as the updated site whenever it appears will hopefully address this issue.
