If I may add my penn'orth from Bulawayo, I hope not. Like other respondents, I check it every day and am always disappointed when there are no new comments. I've contributed occasionally when I think I have something worth saying, either factual or a firmly held opinion (e.g. that Florence Price is vastly overrated), and hope the Message Board will continue to exit, flourish even – and certainly not migrate to Facebook with all its horrors!
One comment while I’m about it: I enjoy the déja vu reviews but wonder on what grounds they are chosen?
