You want a black and white board?
Actually this has already been discussed at http://www.readytogo.net/smb/showthread.php?t=204975
I understand why people want this, but its not on the agenda at the moment. If it was just a one off creation of the skin I would probably do it.
The problem is that several of message board templates (skin) tend to change with each new release of the software we get. Each time there is a new release I therefore have to update these, and the more there are, the more work it is for me.
