Problem exist between chair and keyboard
It was pointed out to me that a entry was missing. My initial reaction was "No, its not!", but then had to confess that yes, an entry that had been posted was missing. This was because I've developed (and written) for blaag on several computers, and I'd accidently made a closed head tip and lost an update. Maybe I need to add some functionality to make sure that existing posts do not disappear.
