I mean, the actual date is 6/6/2006 - the fact that we want to turn it into an abbreviation doesnt make it true, so what I believe is that in the date 662006 nothing will happen, because it is not even a numerical coincidence.
The only cases of 666 dates have already happened, the 6th of June of year 6 AD and the whole year 666.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
