I have left them as a fitting demonstration of the vagaries of e-Trust!
It appears that this blog site does not conform to one of the, as yet un-written, principles of e-Trust.
Namely: Any system that mediates e-Trust will have default settings that are aimed at achieving the highest level of e-trust.
The settings in question were related to the manner in which comments were allowed.
(Alternativley on setting up the site I was not warned of the consequences of changing the settings! I honestly cannot remember which!)
