The INVALID seal

Sites no longer falling within the HONcode perimeter, which we have chosen not to continue to certify, now display the INVALID seal.

Indeed, for various reasons (e.g. a site that has evolved too much since its last certification, a site that no longer meets the HONcode criteria) this site is no longer HONcode certified, and we felt it was essential that this be clearly displayed on the site, for more transparency.
