A class action suit has been filed against Ancestry.com. Subject to final approval of the settlement, anyone who has/had a monthly subscription to their service prior to November 3rd,2005 can benefit. You don't have to prove it either.
They'll be giving 31 days of full access free (among other undisclosed benefits :shrug: )
I currently have a monthly to the US Records just until I get everything I need. I plan to take advantage of the situation. Everyone should get ready to catch up on their research, and put the screws to this monopoly!
