Hmmmm... I usually post to Usenet Groups thru my trusty usenet reader MT
Newswatcher for Mac System 10.4.11.
I check up on the posts in Google Groups. However, recently my "star
rating" history has been deleted. I had several hundred ratings that
'disappeared' into thin air. Is it possible to 'delete' someone elses
ratings, as in a cyber attack?
Or... does Google do a wash-cycle?
