For example, the Black Irish column. Click on the Comment on this Answer link and you get a message saying “No Forum specified. If you followed a valid link, please notify the webmaster.”
Looks like someone hand-coded the link wrong. It should be “…php?forumid=1” instead of “http://boards.straightdope.com/sdmb/forumdisplay.php?s=forumid=1”.
I’ll get it fixed.
Fixed now.
